Hello,

I need to make a cheap fuel cell membrane that is either highly selective to OH- or protons, but preferrably OH-. Also it should have almost no electrolyte crossover.

It would be best if the membrane was made out of a biopolymer, for example alginate or chitin, but it doesn't necessarily have to. Any suggestions, ideas or protocols to it?

Thanks very much,

regards,

André Leonhardt
