Abstract
Ruthenium‐oxide pyrochlore particles were synthesized inside a Dow developmental fuel‐cell membrane (the Dow membrane is a perfluorosulfonated ion‐exchange polymer) by treatment of Ru3+, Pb2+‐exchanged membrane in alkaline aqueous solution with purging of at 75°C for at least 2 days. Compared to our previous work of ruthenium‐oxide pyrochlore electrode attached to a Dow membrane, this work took advantage of incorporating Dow gel, eliminated the reaction‐irrelevant Teflon binder, and simplified the electrode fabrication procedure. Interesting oxygen reduction activity at room temperature was obtained, and the response time for the oxygen reduction reaction was very fast.Keywords
