One thing I've noticed is that when I tried using gold on both sides of the cell, only the oxygen producing side is getting damaged. The hydrogen side looks just fine. I'm having a hard time thinking of a reason other than my gold not being 99+% pure.
Yeah, I'm doing this at home so i don't want to use materials that might produce unwanted toxic byproducts or residue.
Could it simply be that the gold I have is not pure and is an amalgam?
So hardness may be a factor in the durability? Maybe iridium wire would be a solution. Don't know if it can survive such a high oxidation environment though. Maybe platinum/iridium wire.
Well, I tried swapping hydrogen evolution electrodes; tried aluminium and copper, and I get roughly the same result. I've noticed that reheating the gold wire to melting point seems to revert the degradation.
I tried different, weaker voltages(like 5v) and I still get insanely quick...
Help! I was under the assumption that a gold electrode for oxygen would be able to sustain water electrolysis with sodium bicarbonate as the electrolyte without degrading, so I bought a foot long of 28 gauge 24k(pure gold) wire, but I've been putting it to the test for about 30 minutes and it's...
Actually, thinking about it, I think a mesh, especially a fine one, would be worse because it would trap gas bubbles in the mesh, effectively reducing electrode surface area
Really interesting, NiFe oxide seems really simple until you read the paper that was published recently on the subject that explains how these were built. Seems like a REALLY promising approach though, but I don't think I can do this at home.
About this, there are a couple techniques to deal...
This is a DIY home project, so access to exotic materials is quite limited. PEM electrolysis is really interesting, but this isn't something i can build at home. The best i can reasonably get access to is something like those ...
I've been trying to build a closed system water electrolyser with easily available materials which allows me to collect the gases separately. To do so, I've been meaning to build an acrylic housing with a textile separator in the middle of two compartments which houses the anode and cathode. The...
Well if you have, for example, a radio station broadcasting with a circuit operating an antenna at a frequency of 50 Mhz and a 2nd one broadcasting at 100 Mhz, would the 2nd one require twice as much energy as the 1st one if they are both emitting the same amount of photons? If so, it would seem...
Being unsatisfied with the answers given here (it didn't seem quite right), I did a lot more research and yes, radio photons are workable, they are just hard to research because everything at room temperature emits radio photons saturating the environment with a ton of noise. That said, I found...
I'm under the impression that if you increase the frequency of a circuit coupled to an antenna, for the same amount of photons emitted, the frequency of those photons will increase therefore having them carry out more energy total, thus increasing the amount of energy required to power the...
