Interesting idea.
Usually there are 2 types of cat converter, honeycomb and marbles. I'd say you would need the honeycomb style.
Now for the bit that might cause some problems.
While these biscuits do have PMs in them, the main thing they are made out of is some type of ceramic.
So the question is: Will the PMs in the biscuit be enough to make it conductive?
Also whattypeof electrolyte did you have in mind? I would say that you would be better off going with none and using distilled water as the platinum and palladium in the biscuit would turn it into a form of fuel cell.
Palladium loves to absorb hydrogen and we all know that platinum also is used in PEM fuel cells.
It's an interesting thought.
Here's another one along those lines.
Hard drive platters.
The platters in hard drives over the last 10 years have moved away from the old ferrious type and now havve a coating of either cobolt or,in the case of newer drives, platnium. The main component of the platters are usually aluminium or glass but the ones I've pulled apart have always been Al.
So that could be another route to go down. Only really just thought of that one as I was writing this post. Itmay have been tried before, I dont know, but it would be relitivly easy to assemble as theyare all uniform and balanced to spin at high RPMs.
Anyway, it's all food for thought.
