I really liked this video, thank you for sharing it! I've been trying to learn as much as I can about this field for energy self-sufficiency. Wasn't the cell supposed to produce water vapor/droplets and maybe a bit of heat loss as a byproduct? Maybe it was such an inconsequential amount in the short time that the water vapor was too small and evaporated immediately? I might try to repeat your work and include the read out of an infrared thermometer. Thank you again!
Thank you. The byproduct is water and heat, yes. But here on this small cell you will not note a big heat difference. But you can see some small water drops in the cell over 5 hours of run time. Look at the next video,.... where I run the cell with 1 gram of aluminium for more that 5 hours.
$250 for 9W of power seems like a toy. For $250 I think it makes more sense to feed a $50 1HP gas engine with a hydrogen, and attach it to a $100 1kWt generator.
btw, using anything else than carbon as anode (positive) will make recharging not work, because the metal coating will be plated off, and cathode (negative) needs not to be carbon but metal to make metal plating and not metal hydroxide
Good job Sir. So if theoretically we put 50 of this cells in series we should have 45V at 1Amp? Or if we do 50 in parallel 0.9V at 50Amp? Or the cells will be destroyed by the power produced? Thank you
either is fine. In both setups, each cell still has 1 amp flowing through it and .9v across it. You need to size the pair of output wires correctly, depending on which amperage/voltage you choose and distance to load.
@cayrex i made 6 cells using just aluminum foil and carbon... it produces 5 volts constant voltage for 1 week without having to change salt and water... what do you think?
No needed for increased reaction. Because I want to have enough stable hydrogen at slower production rate. That way I can get the hydrogen from water and aluminium for many hours. Increased reaction will produce hydrogen at max for 15 min. In that case, many of the hydrogen will not react in the fuel cell.
Not really,... because aluminium foil or powder (small particles Al) will contribute to faster reaction and faster release of hydrogen. The fuel cell will get the hydrogen how much it needs, but if the hydrohen production is to fast, then most of the H2 will go to the environment. For example: 1 gram of 1mm thich aluminium produce enough H2 that the fuel cell can run for 5 hours. Otherwise a aluminium powder will create a H2 for about 30min.
intéressant! tu crois que tu pourrais l'essayer en photocatalyse avec de l'eau et du graphic carbon nitride pour la source hydrogène? ça semble faisable sans trop de modifications avec ta cellule.... super boulot!
cool! tu en avais tiré de bonnes performances ? ou bien vaut-t il mieux rester sur le système d’électrodes classiques à ton avis? ta chaîne est géniale, merci
maybe, but all that disassembly, sourcing and uncertainty for a delta of 1W - 5W output? i am aware KOH and Al are your energy source, and 1 g of Al is worth less than a fraction of a penny but so is a Watt At kW and kg scale the Al is going to be £1-£10 per hour, and you will need a fuel cell with several hundred platesquestion The interesting question is, imho, would catalysis or electrolysis assist the H2 production, and what size of cell woul
@@cayrex I think it's good that it uses aluminum it's very easy to find garbage. How much power would one aluminum can produce? Whatever it might be I think it's worth it. Also where did you buy the actual fuel cell part at?
@@mikewarren7855 China. Search for Hydrogen fuel cells on Alibaba. Here you will find the cells,.... but the system with the aluminium you will need to make it yourself
