A nickel plaque which may be coated with a suitable metal or compound to make an electrode for a fuel cell or battery is fabricated by directing nickel sensitizer, catalyst and plating solutions through a porous plastic substrate in the order named and at prescribed temperatures and flow rates. A boride compound dissolved in the plating solution decreases the electrical resistance of the plaque. Certain substrates may require treatment in an alkali solution to dissolve filler materials thereby increasing porosity to a required 65%.

Method of making a light weight battery plaque

An improved zinc electrode for alkaline cells includes up to about ten percent by weight of Ba(OH).sub.2.8H.sub.2 O with about five percent being preferred. The zinc electrode may or may not be amalgamated with mercury.
