Electrically balanced fluid manifold assembly for an electrochemical fuel cell system

Abstract

An electrically balanced fluid manifold assembly for supplying a fluid to an electrochemical fuel cell system comprising at least two fuel cell stacks electrically connected in series, each fuel cell stack comprising an inlet fluid port and an outlet fluid port, the manifold assembly comprising: a primary inlet fluid line; a primary outlet fluid line; at least two branch inlet fluid lines, fluidly connecting the primary inlet fluid line to each inlet fluid port of the at least two fuel cell stacks; and at least two branch outlet fluid lines, fluidly connecting each outlet fluid port of the at least two fuel cell stacks to the primary outlet fluid line, wherein the branch inlet fluid lines and the branch outlet fluid lines are configured such that the electrical resistance is essentially the same between (a) each inlet fluid port of the at least two fuel cell stacks and the primary inlet fluid line, and (b) each outlet fluid port of the at least two fuel cell stacks and the primary outlet fluid line.
