Hello,
in cooperation with the company OxFa, I am working on a cheap, functional formic acid/ formate fuel cell. Normally my cells work with a liquid oxidant or a liquid catholyte, but this time I want to work on a different approach, which would be a solid cathode, like in commercial cells. But these typically use expensive monomers to avoid the liquid catholytes. I wanted to ask, if there is another approach for a solid state cathode. I have already thought about using deep eutectic solvents or ionic liquids, but these are mostly (except choline or metal salt based) pretty expensive.
Pay attention to our electrochemical cell, in which the built-in electrodes are wood, saturated with nanoparticles.

@Yuri Mirgorud I have already worked on delignated wood as membrane which worked absoluty great, but there is still a huge water intake and water evaporation which leads to crystallization of insoluble carbonate precipetate.
Wood does not work in our electrochemical cell as a membrane, and it, together with nanoparticles, acts as a cathode and anode.
