    摘要: A gradient of ionomeric material is generated, disposed, or otherwise provided in an electrode suitable for use in a fuel cell. The ionomer concentration, e.g., with respect to the carbon content of the catalyst layer (e.g., expressed as a ratio), is greatest in the area closest to the membrane, e.g., of the fuel cell (e.g., the membrane side), and is decreased in the area furthest from the membrane (e.g., the gas side). By way of another non-limiting example, the ionomer gradient can be formed such that the concentration (or the ratio if expressed in relation to the carbon content of the catalyst layer) can gradually, as opposed to rapidly, decrease as the distance away from the membrane increases.
