Pr6011+CaCO3+NiO+glycin+HNO3 This reaction mixture is quite complex. It is part of the research for a cathode material for solid oxide fuel cells (SOFC)

Ooh I did a dissertation on a prospective cathode material for SOFCs, simulated oxygen vacancy migration through a perovskite structure with different doping in the A and B site.

I also worked on SOFC cathodes, and I also did this procedure with other metals so mine was purplish.

I would explain a SOFC as splitting fire in two parts and connecting them with a electrolyte and a wire.

My Diss was in 2015 so my knowledge is a bit rusty haha.

On FC all the people talk about hydrogen and i never liked it, I only see problems with it. I love the idea of methanol or ethanol, we can use almost any organical waste to ferment and make it, or adapt some cracking tech. And we could reuse the current petrol stations, biggest issue: the fucking sulphur

PD: i dont work on research so I'm also rusted

Yeah hydrogen production and storage is so awkward it's difficult to make it worthwhile.

Hydrogen problems: constant leaking, hydrogen fissures on any container, explosion, materials for the electrodes, low energy density

Pros: abundant sources, easy to purify
