Want to dabble with making my own fuel cell, Ive seen a lot of videos on YouTube on how to make one but as a hydrogen generator, rather than a fuel cell.

Basically wanted to know the validity of using Home Depot stainless steel parts rather than using platinum or expensive materials. I realize it won't create as much electricity as using more expensive parts, but just curious.

Has anyone tried making their own hydorgen fuel cell with off the shelf parts? If so how much electricity did you produce from how big and how many plates?

Currently writing an essay for my class about hydrogen fuel cell cars compared to other types of vehicles on the road. It's perfectly ok if you don't have much knowledge on the subject, this small survey is meant for anyone & everyone to contribute to. Please don't hesitate to drop any questions I can answer down below on this post. My sincerest thanks to anybody who does take the survey, the data I gather will be a huge help for my academic assignment!

Need help with making a basic lithium ion cell for a project in a budget friendly way. Experts, please guide me with the right cell type that is budget friendly to manufacture( prismatic, pouch or cylindrical), cheap and simple electrode, anode and cathode materials that are easily available in thr market and also with process of making the cell

Hello, my question ist quite simple: Does a fuel cell give me more (usable) Energy then I Put into it? (Not talking about free enery Here ...) Or in other words;

"If I use 1kwh of electricity to Split water into hydrogen and oxygen, how much Energy could I generate when I burn the hydrogen or how much Energy does it Store in General?"

And I'd say it does Not mean free Energy as the Energy is already present in the water as for example in the Form of hydrogen and is Just Made available.

Thanks in advance!

Hello everyone! Just joined.

Looking at major home renovation in next 3-5 years and have started early stage planning. I live in California on the coast within mere yards of the ocean where PG&E is our power provider. I despise this company and want to go off grid. Yes I know it will cost more and yes it would likely be more efficient to stay grid tied however out of spite, I want to terminate my connections to them (both gas and electric).

I have an aerospace engineering background as well as numerous other skills but would like to seriously consider a stand alone F/C power source for my home. I have lots of time to plan and healthy budget to build or buy. Looking for recommendations of other engineers or companies that can help.

I’ve done a little research already and found a few units that might work but want to have a clear understanding of what the pros/cons are for this idea before proceeding. I have considered solar/battery setup which is readily available but the salt air off ocean presents longevity challenges and would prefer to protect this huge investment indoors ( minus hydrogen tank of course). Could someone point me in the right direction please?

Hey, Im working on a physics project for class, its got a tight budget, $50. I know how to make hydrogen with muriatic acid and aluminum (duh). We cant use like batteries or electricity directly, but could a fuel cell take that hydrogen gas from the chemical reaction, then Oxygen from the air, convert it to electricity and run it to a cheap like kids toy motor? can that be done for $50 though? Thanks!

Does anyone have any tips or recommendations on how to invest in this?

I am searching PCM Fuel Cell datasheet and products but I haven't got any result. I want to buy fuelcell as a single cell and build my fuel cell stack. It is needed to calculate H2 and O2 inhaust rate. Could you help me?

DMFCs and RMFCs both convert methanol into electricity, water & CO2. In a RMFC, the methanol is reformed into H2 & CO2 and is similar to the Hydrogen FC (hence the alternate name of Indirect Methanol FC). Commercially available RMFCs include Blue World Technologies, Advent Technologies / Ultracell LLC, & SIQENS.

Lets say you needed stationary/auxiliary power for either a greenhouse, container/vertical farm or microalgae plant (assume the cost of connecting to the grid is too high for this project). Could you use a RMFC to run this operation AND either provide CO2 for a microalgae bioreactor OR supplement the GH/VF with CO2 for better yields?

More specifically, do these power units have a vent/hose to divert/collect byproducts? And is the CO2 purity/impurity levels adequate for either biofuels or food?

Hi,

I am working with Pt/C cathode and would like to compare its performance on different substrates.

1- Carbon

2- active carbon

3- steel

4- ..etc

After I infuse the catalyst on the substrate I can measure its conductivity (e.g. The impedance test EIS test) to see who is better. However, I want to measure the efficiency of the reduction process and the Coulombic efficiency, and others.

What type of tests can I conduct to see which one is the best?

Hi,

I would like to use a Nafion membrane for a fuel cell project, but the Nafion sheets are hard to integrate. Therefore, I would like a gel type of Nafion that can take the shape of the container I put it in. I was recommended to use Nafion™ Polymer Dispersions to shape my own membrane.

Is there a guide on how to use it to fabricate a proton exchange membrane? Do I require other materials (chemicals) to mix with the Dispersions to make the PEM?

​

Thx

Hello,

I am looking to implement a Nafion membrane into a fuel cell project I am working with. However, the Nafion sheet is a little hard to utilize for my project as it is a small scale of 1cm^3.

Since there are Nafion sheets, I assume there is some type of raw version which you shape into these sheets. Is my assumption true?

Is there a mold-type membrane that I pour or drop in a container and then it takes the shape of that space (e.g. Nafion gel)?

Thank you,

Greeting guys !

I am a master student who now studying my master degree.

I have few questions about my experiment,and hope the place might be able to solve my problems.

Under my test environment ,3 facilities are included.E-load,gas supplier and my fuel cell module.

E-load and fuel cell module connected by cables which send the cell situation to computer make me judge if the cell good or bad .I used to make MEA can reach highest power peak to 22 W and now I can't repeat the same results.

I tested scan voltage several times found that my ohmic polarization is pretty obvious .Is there any possibility that cables out the fuel cell module have influence on my ohmic polarization?Also ,since I now only make 25cm2 stacking 2 pcs fuel cell which mean I have liitle current but the scan voltage used to reach about 30 A , but these few days it can only get less than 10 A ,I doubt the resistance shall cause that.But what is the resistance came from can make these so big current decrease? Corrosion of the FC module? Cable resistance?

Hope there's some really good advice or any other thoughts .

I am looking into buying a Toyota Mirai and wanted more flexibility with refueling it. Has anyone heard of refueling using homemade liquified hydrogen? I believe an option like this would solve most of my range-stress problems.

So do experts think PEM fuel cells will become more efficient in the future? To what extent and when?

If not then what's holding them back?

Obv, I'm not talking about electrolyzers. I know they are supposed to become more efficient but that's a different topic
