ABSTRACT:
A porous electrode, possessed of good physical qualities, containing size optimized electrocatalyst-bearing pores ensuring suitability for electrochemical reaction promotion, including the electroreduction of oxygen in alkaline media, is comprised of the compressed and compacted product of a pre-catalyzed, volumetrically reduced pre-form structure that, prior to densification, was characterizable in being laced with precursive interstitial passageways that are larger than electrode body pore size and which are comparably of a more open catalyst-applicating accessibility which passageways had been pre-provided on their wall surfaces with effective quantity deposits of catalytic agent.
