Abstract:
1. An electrode for a fuel cell, the electrode comprising a catalyst layer including a mixture of: a catalyst; a binder, the binder being at least one of styrene-butadiene rubber (SBR), the styrene-butadiene rubber (SBR) consisting of carbon and hydrogen, and polyurethane; and a pyrrole-based compound represented by Formula 1 below: wherein p, q, r and s are each independently 0 or 1 and described below: when p=q=r=s=0, R when p=1 and q=r=s=0, R when p=q=1 and r=s=0, R when p=q=r=1 and s=0, R when p=q=r=s=1 and R wherein paragraph i) and ii) are as follows: i) a hydrogen atom, a halide, a hydroxyl group, a C1-C20 alkyl group, a C2-C20 alkenyl group, a C2-C20 alkynyl group, a C6-C20 aryl group, a C7-C20 alkylaryl group, a nitro group, a formyl group, a C1-C20 acyl group, a C1-C20 hydroxyalkyl group, a C1-C20 alkoxy group, a C1-C20 hydroxyalkoxy group, a C2-C20 hydroxyalkenyl group, a C2-C20 hydroxyalkynyl group, a C1-C20 alkylcarboxyl group, a carboxyl group, and an amide group, and ii) a hydrogen atom, a C1-C20 alkyl group, a C1-C20 alkylsulfone group, a C1-C20 carboxyalkyl group, a C1-C20 carboxyamidealkyl group, and a C6-C20 aryl group.
