Abstract
A reactant flow system for a proton exchange membrane (PEM) fuel cell stack using a water-soluble fuel is described. The flow system includes the use of single-pass or multi-pass, flow channels. A flow channel section having at least one adjacent channel section whose reactant flows in an opposite direction thereto. The system has respective reactant inlets that are effectively adjacent to reactant outlets of the adjacent channel section. Restrictions are used at the reactant inlets to assure substantially uniform reactant flow among all of the flow channels.
