电极用催化剂、气体扩散电极形成用组合物、气体扩散电极、膜/电极接合体以及燃料电池组
摘要：
本发明提供一种即使含有较高浓度的氯也能够充分发挥性能，且适于批量生产，并且适于降低制造成本的电极用催化剂。该电极用催化剂为具有包括载体、被形成在所述载体上的芯部以及以包覆所述芯部的表面的至少一部分的形式所形成的壳部的芯/壳结构的电极用催化剂，且为同时满足以下述式(1)和下述式(2)所表示的条件的电极用催化剂。[在所述式(1)和式(2)中，M表示为所述壳部的构成金属元素的物质量(原子数)，X1表示为溴(Br)的物质量(原子数)，X2表示为氯(Cl)的物质量(原子数)。](X1/M)≤1.2…(1)；(X2/M)≤47.0…(2)。
摘要（英）：

Provided is a catalyst for electrodes that is capable of exhibiting sufficient performance, even if containing a comparatively high concentration of chlorine, is suitable for mass production, and is suitable for reducing production costs. The catalyst for electrodes has a core-shell structure including a carrier, a core section formed upon the carrier, and a shell section formed so as to cover at least part of the surface of the core section. The catalyst for electrodes simultaneously fulfills conditions indicated by formula (1) and formula (2). (X1/M) < = 1.2 ... (1); (X2/M) < = 47.0 ... (2). [In formula (1) and formula (2), M indicates the amount of constituent metal atom material (number of atoms) in the shell section, X1 indicates the amount of bromine (Br) material (number of atoms), and X2 indicates the amount of chlorine (Cl) material (number of atoms)].
