description The invention is a fuel cell stack having an improved pressure plate and current collector. The fuel cell stack includes a plurality of fuel cell component plates stacked adjacent each other to form a reaction portion of the fuel cell stack. A current collector is secured adjacent a first end of the stack of fuel cell component plates and a pressure plate is secured adjacent to the current collector. The current collector is made from a non-porous, electrically conductive graphite material and includes at least one conductive stud secured to the collector. The pressure plate is made of an electrically non-conductive, non-metallic, fiber reinforced composite material, so that the current collector and pressure plate are light, compact and have a low thermal capacity.
