Abstract
The present invention relates to a method for operating a fuel cell (1) of a fuel cell system (2) for a vehicle. According to the method, a predetermined load reduction is implemented in stages so that, combined with cooling of the fuel cell (1), unacceptable operating conditions, which can, for example, lead to increased wear of the fuel cell (1), are avoided. The invention also relates to a fuel cell system (2) for a vehicle.
Claims10
A method for operating a fuel cell (1) of a fuel cell system (2) for a vehicle, the method comprising:
- operating the fuel cell (1) with a first load (L1) at a first temperature (T1) by a control device (3) of the fuel cell system (2),
- receiving a load requirement for operating the fuel cell (1) with a second load (L2) by the control device (3), wherein the second load is less than (L2) the first load (L1),
- selectively reducing the load of the fuel cell (1) to a third load (L3) by the control device (3), wherein the third load (L3) is less than the first load (L1) and greater than the second load (L2),
- cooling the fuel cell (1) to a second temperature (T2), and
- reducing the load of the fuel cell (1) to the second load (L2) by the control device (3).
