Aluminate is totaly inert much like silicate but it can give problems if it happens to crystallize out of solution on the electrodes impeding gas access.if the NaOH sol volume is large enough and at right concentration it won't crystallize.

And your PdCl2 solution can be very handy later on mr pomodoro (-: you can also leach Pd out of 10% Pd/C using aqua-reg.

If I have some time I'll send photos of the proposed setup. Once we agree on a foolproof cell I will proceed. I was thinking of bonding the Pd on C to a pt electrode with silver loaded epoxy if these initial experiments go well.

I was going to ask you about photos,that would add some spice to this thread for sure.don't bother epoxying anything mr pomodoro its going to have to be a tight adhering electroplate of Pd black.I used to burn conc PtCl2 syrup directly ontop Pt foil and it would decompose into the most beautiful grey sponge coat.I'm not sure if we can do this with PdCI2 but we can definitely do it with ammonium palladium chloride (this is how they prepare industrial catalysts) I just have to google quick to double-check on the decomposition products of PdCI2

PdCI2 decomposes to Pd sponge and Cl2 gas at 650 degrees C so a bunsen flame should be able to do it.ammonium chloropalladate precipitated from PdCI2 soln and a few drops ammonia soln melts then decomposes directly to sponge at low temp,300degrees
