title = "Investigation of problems at the PEFC cathode layer under higher temperature operation",
abstract = "Toward the development of electrocatalysts for future higher temperature PEFCs, extraction of critical issues for higher temperature PEFCs was aimed. Degradation phenomena and mechanisms at 105°C were evaluated for both Aquivion{\textregistered} MEA and Nafion{\textregistered} MEA. The correlation between proton conductivity and changes in cathode structures on the acceleration degradation test was studied in detail. As a result, even though the macroporous structure of the cathode layer was homogeneous in Aquivion{\textregistered} MEA, larger pores almost intensely formed near the Nafion{\textregistered} membrane side. We have found that the carbon oxidation reaction is deeply related to H2O produced by a fuel cell reaction if it is under the low humidification condition. Therefore, when proton conductivity is low like Nafion{\textregistered} MEA, H2O is mainly generated at the interface between the cathode layer and Nafion{\textregistered} membrane and carbon oxidation intensely occurs at the interface.",
