Method for preheating at least one fuel cell of a fuel cell system, in particular a high-temperature fuel cell system of a vehicle, and corresponding fuel cell system

摘要

The method is used for preheating at least one fuel cell (13) of a fuel cell system (10), in particular a high-temperature fuel cell system of a vehicle to a predetermined operating temperature and for subsequent commissioning of the same fuel cell (13), the following process steps are provided: DOLLAR A - heating a gaseous preheating medium flow of the fuel cell (13) in a gas supply unit (14), in particular by means of at least one preheating medium compression; DOLLAR A - supplying the heated preheating agent in the fuel cell (13), which is not in operation for generating electricity, until a sufficient operating temperature has been reached; DOLLAR A - Commissioning of the preheated fuel cell (13) for power supply by means of at least one operating medium flow (20, 48).
