    • An electrode, a method of producing the same, and a fuel cell including the electrode are disclosed. The electrode includes: a support; and a catalyst layer formed on the support, the catalyst layer includes: a support catalyst; and a proton conductor having an amorphous phase greater than about 60% by weight. The proton conductor includes: at least one material from the group of B2O3, ZrO2, SiO2, WO3, and MoO3; and P2O5, the proton conductor being 0.5-60 parts by weight where the support catalyst is 100 parts by weight. The proton conductor can be synthesized at a low enough temperature so that it can be applied to the support with catalyst particles to form a catalyst layer. The coated proton conductor is in a solid state so the fuel cell is stable over time and it does not obstruct a fuel gas so that the catalyst can be more efficiently used.
    • 公开了一种电极及其制造方法以及包括该电极的燃料电池。 电极包括:支撑体; 催化剂层,其形成在所述载体上,所述催化剂层包括:载体催化剂; 和具有大于约60重量%的非晶相的质子导体。 质子导体包括:至少一种来自B 2 O 3 3,ZrO 2,SiO 2,SO 2, >,WO 3和MoO 3; 和P 2 O 5 O 5,质子导体为0.5-60重量份,其中载体催化剂为100重量份。 质子导体可以在足够低的温度下合成,使得其可以用催化剂颗粒施加到载体上以形成催化剂层。 涂覆的质子导体处于固态,因此燃料电池随时间稳定,并且不阻碍燃料气体,从而可以更有效地使用催化剂。
