Electrically-conductive, hydrophilic and acid-resistant bipolar plates for PEM fuel cells.
This type of metal plate has a chem.-modified metal oxide coating. The modified metal oxide coating advantageously has a predetd. contact angle and is elec. conductive. The modified metal oxide is prepd. by treating an unmodified oxide with a chem. soln. and/or by heating. [on SciFinder(R)]
