Fuel cell system

Abstract

Title: Fuel Cell System The invention relates to a fuel cell system (1) having a "ping-pong" architecture, in which two groups (10, 20) of electrochemical cells are alternately fed by a fluidic circuit (3, 4) comprising at least one expansion member and two switching members on the group supply lines (100a, 200a). Advantageously, the switching members are formed by proportional valves (101, 201) configured to expand the feed fluid from a main conduit (300a). The proportional valves (101, 201) both expand the fluid and progressively allow or block the flow of fluid to the inlets (11, 21) of the groups (10, 20). Figure for the abstract: Fig. 2A
