1. A fuel cell system for air vehicles,
wherein the fuel cell system comprises:
a fuel cell,
an oxidant gas system for supplying oxidant gas to the fuel cell,
an altitude sensor, and
a controller;
wherein the oxidant gas system comprises an air compressor and a bypass flow path bypassing the fuel cell;
wherein the bypass flow path comprises a bypass valve; and
wherein, when the controller detects an altitude increase measured by the altitude sensor, the controller increases a rotational speed of the air compressor, and the controller increases an opening degree of the bypass valve.
