A method for operating a fuel cell

A method for operating a fuel cell system comprising one or more fuel cells below a predetermined maximum polarisation cell voltage limit wherein, for each set of one or more operational conditions of the one or more fuel cells, said predetermined maximum polarisation cell voltage limit corresponds to a minimum power limit, and wherein said set of one or more operational conditions comprises at least the temperature of the one or more fuel cells, said method comprising:

• receiving a power request for execution at an execution time,
• in response to detecting that the power request is lower than an estimated minimum power limit corresponding to an estimated set of one more operational conditions at said execution time, said estimated set comprising an estimated temperature,
• performing an adjustment of least one out of said one or more operational conditions to achieve an adjusted set of operational conditions at which the minimum power limit is lower than said estimated minimum power limit;
• wherein
• said adjustment comprises cooling said one or more fuel cells to a reduced temperature being lower than said estimated temperature.
