Fuel cell system

Abstract

Fuel Cell System This fuel cell system (1) comprises a fuel cell (10), a hydrogen circuit (20), and a cooling circuit (40). A supply line (21) of the hydrogen circuit is provided with a mixer (21.1) for mixing hydrogen from a reservoir (2) and hydrogen recirculated from an anodic outlet (12) of the cell, as well as a heat exchanger (21.5), upstream of the mixer, for heating the hydrogen from the reservoir. The cooling circuit includes a supply line (41) connecting a radiator (3) to a cooling inlet (15) of the cell, a return line (42) connecting a cooling outlet (16) of the cell to the radiator, and a branch (46) connecting to the return line, forming a closed loop upstream of the radiator.The branch connects the heat exchanger in parallel to the return line so that the heat exchanger transfers heat to the hydrogen from the tank, using a portion of the cooling fluid from the cooling outlet. See Figure 1 for abbreviations.

Claims

radiator (3) and in the bypass line (43), and in which the loop formed by the branch (46) is closed on the return line (42) upstream of the connection of the bypass line (43) to the return line.

8. Fuel cell system according to any one of the preceding claims, in which the mixer (21.1) is a Venturi ejector which is adapted to drive into the recirculation line (22) the flow of hydrogen (H2) recirculated from the anode outlet (12), by Venturi effect.
