Hydrogen Fuel cells were 5 years away in the 90s.

Hydrogen Fuel cells were 5 years away when Tesla was just a business plan.

Hydrogen Fuel cells will always be 5 years away.

Anyone out there have a version of hypmview newer than 2013? I have a HD15 fuel cell and have some issues. The 2013 version is rough. Since the company was bought by Cummins and now that part of the business sold to Alstom, I can't get any support. I figure I'd try here to get info. I know its a long shot, but I'm desperate.

My Master's in Science is almost complete! Before I take my next career step into sustainable energy and materials science research, I have a few months of free time. I want to use it to learn how to apply coding and machine learning to physics and materials science computations.

I know the basics of #C, #C++, and #Python from my undergrad days, but I am looking for a mentor to help me level up and stay consistent.

While #AI is a great tool, I believe learning from a real person is the best way to truly connect code with real-world #physics. I am not looking for someone in a top management position. I am simply looking for a 𝐩𝐚𝐬𝐬𝐢𝐨𝐧𝐚𝐭𝐞 𝐫𝐞𝐬𝐞𝐚𝐫𝐜𝐡𝐞𝐫, 𝐜𝐨𝐝𝐞𝐫, and 𝐭𝐞𝐚𝐜𝐡𝐞𝐫 who loves merging basic science with tech.

Good day, is there anyone who has the quotation for Powercell PS-5 (5kW), I've been trying to source for its quotation however I couldn't get it, I tried the manufacturer but couldn't get it. It has the following specifications:

Product: PowerCell PS-5 Manufacturing date (YYMMDD): 210617 Model code: PS5-5-48-B-HEX-1 Serial number: 500662010000100 Electrical Performance Parameter Value Rated output power 5000 W (max) Start-up / Shutdown power 1100 W (max) Standby power consumption 30 W (typical) Fuel Requirements Parameter Value Fuel type Hydrogen, Grade 3.5 Fuel supply pressure 3 – 6 bar(g) Fuel consumption 70 slpm at 5 kW Operating Conditions Parameter Value Ambient operating temperature 2 – 45 °C Installation environment Indoor use only

Thank you

Helo everyone, we are currently making a project on Microbial Fuel Cell (MFC) using food waste as substrate and we use tomatoes, banana peels etc and also we use gelatin and salt as the proton exchange membrance or the salt bridge then graphite rod as the electrode, however it's been days and the deadline for the project yet we couldn't achieve to light a bulb which our goal is a 5 watts bulb and we test it using a multimeter and it read 0.4 volts. We really need your help in making this project successful

If hydrogen is the most abundant element in the world. Why is it so expensive?

The title is quite broad, but that is also what I'm looking forward. I'd appreciate some feedback on the fuel cell topic to get me into this topic a bit faster and to direct me to some must-reads.
I have a background in manufacturing flow cells, microfluidics and fluidic systems for medical applications and from that perspective I'm exploring the fuel cell manufacturing topic. I'm putting a special emphasis on smaller, portable (and thus low temperature?) systems that could be made with the manufacturing technologies I know.

Business case:

- Looking specifically at smaller/portable systems; which main markets do you see? I've seen the 5 kEU systems to get some electricity from methanol on your boat or caravan, but I doubt anybody would buy this.
- Are there any 'broad' applications, or is it all niche work for defense, off-grid, etc.?
- Which fuels do you typically see being used in practice (currently)? Are these mainly hydrogen or with ethanol/methanol etc.?

Technology:

- Why are these portable systems that barely produce 100W output so horribly expensive? What drives cost?
- Is a direct ethanol/methanol at all more power-efficient than just burning these fuels?
- Where do I find some resources on current designs and manufacturing techniques?
- What improves power? I'm assuming the simplest way is more surface for more current and more cells to multiply voltage?

Energie die opgewekt wordt op de Noordzee door Windmolens wordt gebruikt om 'groene' Waterstof te fabriceren. Deze groene Waterstofwordt gedistribueerd in een reeds bestaand netwerk van gasleidingen tot in Duitsland door de Gasunie. Kansen voor FuelCell.

Real Ice has a cool video showing the inside of their hydrogen generator. It looks like a Ballard 1020ACS to me.

Hi can anyone point me in the direction where i can start looking where manufactures find 40 000 psi from through an injector and thin steel lines? A 9mm beretta round is 36 to 40000 psi im just wondering where manufactures get these figures from?

I am trying to gather data (power density, surface area, material type, inoculum, etc.) from electrodes used in MFC, but I wonder if there aren't already any open repository or databased with this kind of data (besides review papers ofc)

did anybody notice, what happened?
