本文研究了Ni2P、CoP、FeP、WP和MoP等金属磷化物作为中温燃料电池阳极催化剂。以CsH2PO4和SiP2O7、金属磷酸盐和商用Pt/C电极组成的复合电解质分别作为电解液、阳极和阴极，并在220ºC下作为H2-O2燃料电池进行发电特性评估。通过循环伏安法测定各阳极的电化学表面积，比较了各阳极的性能。在磷化物阳极中，MoP催化剂表现出优异的电流-电压特性，表现出优于Pt/C催化剂的阳极催化剂潜力。
In this study, metal phosphides such as Ni2P, CoP, FeP, WP, and MoP were investigated as novel anode catalysts for intermediate temperature fuel cells. Composite electrolytes composed of CsH2PO4 and SiP2O7, the metal phosphates, and a commercial Pt/C electrode were used as the electrolyte, anode, and cathode, respectively, and power generation characteristics were evaluated at 220ºC as H2-O2 fuel cells. The anode performance was compared based on the electrochemical surface area of each anode determined by cyclic voltammetry. Among the phosphide anodes, the MoP catalyst exhibited excellent current-voltage characteristics, and demonstrated a potential as an anode catalyst superior to the Pt/C catalyst.
