Abstract
The invention relates to a method for operating a fuel cell (2), which is to be implemented by means of a control computer (10) that drives the level of current generated by the cells of the fuel cell, said fuel cell including a means for tracking the temperature of the cells, said method being characterized in that it comprises the following steps: when starting the operation of the fuel cell, if the temperature of the cells is at a sufficiently low level, particularly less than 0° C., driving a series of cycles of current intervals including, alternately for each cycle, a low non-zero current (Imin), and then a current interval comprising raising and lowering the strength of the current at programmed speeds.
