使用加有晶种的电极借助核壳催化剂对高性能燃料电池电极的卷对卷制造
摘要：
一种用于形成燃料电池催化剂的方法包括形成包括碳颗粒和离聚物的含离聚物层的步骤。将钨镍合金颗粒形成在碳颗粒上。钨镍合金颗粒中镍的至少一部分采用钯替换以便形成涂覆钯的颗粒。该涂覆钯的颗粒包括覆盖该钨镍合金颗粒的钯壳。该涂覆钯的颗粒涂覆有铂形成电极层，其包括分布在其中的核壳催化剂。
摘要（英）：

A method for forming a fuel cell catalyst includes a step of forming an ionomer-containing layer including carbon particles and an ionomer. Tungsten-nickel alloy particles are formed on the carbon particles. At least a portion of the nickel in the tungsten-nickel alloy particles is replaced with palladium to form palladium-coated particles. The palladium-coated particles include a palladium shell covering the tungsten-nickel alloy particles. The palladium-coated particles are coated with platinum to form an electrode layer including core shell catalysts distributed therein.
