摘要： An exemplary fuel cell component includes a generally planar body having a total area defined by a length and width of the body. A first portion of the total area is occupied by a first fuel cell features that renders the first portion unusable for at least one fuel cell function. A second portion of the total area is occupied by a second fuel cell feature that renders the second portion unusable for the fuel cell function. A third portion of the total area is considered an active area of the component that is useful for the fuel cell function. An aspect ratio of the length to the width of the generally planar body is dependent on a dimension of the first portion and a dimension of the second portion.

摘要： An exemplary flow field includes a plurality of flow channel portions. There are n inlet portions configured for introducing a fluid into the flow field. A plurality of first pass portions direct fluid flow in a first direction. A plurality of second pass portions direct fluid flow in a second direction that is generally parallel to and opposite to the first direction. A plurality of third pass portions direct fluid flow in the first direction. n outlet portions are configured to allow fluid to exit the flow field. n is an integer and a number of the portions in at least one plurality of pass portions is a non-integer multiple of n.

摘要： An electrode for an electrochemical cell includes platinum catalysts, carbon support particles and an ionomer. The carbon support particles support the platinum catalysts, and the ionomer connects the platinum catalysts. The electrode has a platinum less than about 0.2 mg/cm2 and an ionomer-to-carbon ratio between about 0.5 and about 0.9. A membrane electrode assembly includes a proton exchange membrane, a cathode layer and an anode layer. The cathode layer includes platinum catalysts, carbon support particles for supporting the platinum catalysts and an ionomer connecting the platinum catalysts. The cathode layer has a platinum loading less than about 0.2 mg/cm2 and an ionomer-to-carbon ratio between about 0.5 and about 0.9. The anode layer includes platinum catalysts, carbon support particles for supporting the platinum catalysts and an ionomer connecting the platinum catalysts.
