Abstract
EARLIER publications have shown that the ‘Teflon’-bonded platinum black electrodes developed by Niedrach and Alford1 for use in fuel cells with aqueous electrolytes are mechanically stable over a temperature range from 25° to 200° C and perform well with both oxygen and air and with a variety of fuels and electrolytes1–6. This communication presents the initial results that we have obtained using these electrodes in a fuel cell operating with gaseous ammonia and oxygen and using 54 weight per cent aqueous potassium hydroxide as electrolyte. Similar results have been obtained with aqueous caesium hydroxide as electrolyte7. The cell and auxiliary electrical equipment were essentially the same as those used for the methanol–oxygen fuel cell2.
