摘要：

To　study　the　effect　of　copper　ion　on　the　membrane　electrode　assembly　(MEA)　of　a　proton　exchange　membrane　fuel　cell　(PEMFC)　and　the　recovery　method　of　performance　of　PEMFC　with　the　MEA　that　was　eroded　by　the　copper　ion,　the　contamination　on　the　surface　of　the　MEA　was　examined　by　the　X-Ray　Diffraction　(XRD)　and　the　boiling　method　to　renew　the　performance　of　MEA　was　performed.　In　experiments,　it　is　found　that　the　metal　polar　plates　were　eroded　because　of　some　flaws　on　gold　film　of　the　plates,　and　the　copper　ion　dramatically　influenced　the　performance　of　the　MEA.　The　experimental　results　indicate　that　the　method　of　boiling　MEA　in　0.2　m　diluted　sulfuric　acid　could　take　off　copper　ion　from　MEA　surface　and　renew　the　performance　of　MEA.　The　effect　of　the　method　for　separated　membrane　electrode　assembly　is　better　than　that　for　hot-pressed　sandwiched　membrane　electrode　assembly　because　the　hydrophobicity　of　carbon　paper　could　be　poorer　after　the　carbon　paper　is　boiled　in　diluted　sulfuric　acid.
