Method for temperature control in a fuel cell system and fuel cell system

摘要

The invention starts from a method for temperature control in a fuel cell system (2) comprising at least one fuel cell module (4, 6) and one cooling device (10) for cooling the fuel cell module (4, 6), in which coolant is passed through the fuel cell module (4, 6) and a processing means (8) controls a temperature of the coolant. In order to avoid a temperature increase in a fuel cell module in the event of a strong current gradient, it is proposed that a change in the electrical current (I1, I2) is used by the fuel cell module (4, 6) as a correction parameter for purposes of control.
