FUEL CELL SYSTEM AND MOBILE BODY

摘要

A fuel cell system (1) is provided with a fuel cell (10); a fuel supply system (3) for supplying the fuel cell (10) with a fuel gas; an injector (35) for adjusting a pressure on the upstream side of the fuel supply system (3) and supplying the gas downstream; a control means (4) for controlling the injector (35) to be driven in a prescribed drive cycle. The control means (4) sets the operation status of the injector (35) corresponding to the operation status of the fuel cell (10). The operation status of the injector (opening degree of an injector valve (gas passing area), open time of the injector valve (gas injecting time) and the like) can be set corresponding to the operation status of the fuel cell (electricity generated by the fuel cell (power, current and voltage), fuel cell temperature, abnormal state of the fuel cell system, abnormal state of the fuel cell main body, and the like). Thus, supply pressure of the fuel gas can be suitably changed corresponding to the operation status of the fuel cell, and response can be improved.
