电极催化剂和其制法、及含其的膜电极组件和燃料电池
摘要：
电极催化剂和其制法、及含其的膜电极组件和燃料电池。该电极催化剂与目前市售的Pt/C催化剂相比具有优异的电化学活性且比使用铂的催化剂便宜得多。该电极催化剂包括具有约10-约30m2/g的比表面积的碳化钨和包含钯(Pd)或钯合金的金属催化剂。
摘要（英）：

The invention discloses an electrode catalyst and a method of preparing the electrode catalyst, and a membrane electrode assembly and a fuel cell including the electrode catalyst. The electrode catalyst has excellent electrochemical activity compared to the currently commercially available Pt/C catalyst and is much cheaper than a catalyst using platinum. The electrode catalyst includes tungsten carbide having a specific surface area of about 10 to about 30 m2/g, and a metal catalyst comprising palladium (Pd) or palladium alloy.
