    Graphite coated electrodes

    Merely a thought as I was browsing McMaster's, what about using graphite as an electrode? It shouldn't react with most electrolytes. I wonder if it would be possible to powdercoat cheap metal sheets with something like McMaster's dry lubricants which they claim is conductive to have a longer-lived and very cost-effective cell.

    Your thoughts?

    I Tried 4x6" 1/8" thick graphite plates. They worked good but the positive plate breaks down fast. I ran the cell at 40 Watts for about an hour and aprox 10% of the plate ended up on the bottom of the cell. The advantage of graphite is that you can keep the power down due to the resistance.
