可逆式再生氢氧燃料电池初步研究

Primary Research of Reversible Proton Exchange Membrane Regenerative Fuel Cells

再生氢氧燃料电池（ＲＦＣ）是一种将水电解技术与氢氧燃料电池技术相结合的可充放电池，使２Ｈ２＋Ｏ２→２Ｈ２Ｏ＋电能与其逆过程得以循环进行，换言之，氢氧燃料电池的燃料氢气和氧化剂氧气可通过水电解技术得以“再生”，起到蓄能作用．ＲＦＣ主要用于航天领域，与目...

In this paper, we report the results of our studies on regenerative proton exchange membrane fuel cell(RPEMRFC) catalysts, electrode preparation and their performances. The Pt catalyst for the oxygen electrode was replaced by 60 w%Pt+40 w%IrO 2 which reduces polarization by 0.2 V in a polymer protone exchange membrane fuel cell. The cycle performance of RPEMRFC was found to be manly effected by the stability of the diffiusion layer of bifunctional oxygen electrode.
