Abstract
A fuel cell stack includes a plurality of adjacently stacked fuel cell modules each of which includes a plurality of adjacently aligned fuel cells that are connected in electrical series. The current flow between adjacent fuel cells is achieved across diffusion media of said adjacent fuel cells. First and second reactant channels are formed in the reactant carrier plates for separately delivering two different reactants along each reactant carrier plate.
