A fuel cell electrode is made by plating a suitable conductive base material e.g. boron or silicon carbide, carbon or platinum, with platinum applying a pulsed D.C. current at 1 to 6 A.S. cm. at low frequency e.g. 30 c.p.s. for .2 to 5 mins. The pulses are of .1 to 2 milli-seconds duration. The anode of platinum or other conductive material is immersed in chlorplatinic acid and is of substantial area in relation to the working electrode being formed. Promoter metals e.g. Ru, Rh and Au may be co-deposited using additional anodes of the metal and adding the metal chloride to the electrolyte. |
