Fuel cell system

Abstract

A fuel cell system includes: a fuel cell stack; a cathode gas supply flow path connected to the fuel cell stack; a cathode off-gas discharge flow path connected to the fuel cell stack; a bypass flow path connecting the cathode gas supply flow path and the cathode off-gas discharge flow path so as to bypass the fuel cell stack; a bypass valve provided in the bypass flow path and including a valve body configured to rotate to adjust a gas flow rate; and a first plate-shaped part for rectification provided in a part of the bypass flow path downstream of the valve body, wherein the first plate-shaped part for rectification includes a first proximal end adjacent to an outer edge of the valve body positioned at a predetermined rotation angle and extends along an extension direction of the bypass flow path.
