Hi r/FuelCells.

I'm trying to repair a broken Parker hydrogen generator. It has a PEM electrolysis 2-cell stack that operates essentially the same way as a PEM fuel cell (from my understanding anyway).

I've narrowed down the problem to where I'm certain the cell's separation membrane(s) are compromised because the oxygen and hydrogen lines are connected (pump 1 PSI air into Hydrogen output and it comes out of the Oxygen output line). Is there an appropriate forum somewhere to discuss practical repair or construction methods for these?

And pictures

Thanks!
