Operating fuel cell with which cell on one side is supplied first fuel also on other side is supplied oxygen for catalytic oxidation

摘要

The method of operating the fuel cell (1) is carried out so that when needed a second fuel (14) is supplied. The first fuel (13) is methanol and the second fuel (14) is hydrogen. The second fuel (14) is supplied to the fuel cell (1), dependent on the load. The second fuel (14) is supplied as soon as the voltage of the fuel cell (1) fails to reach depending on the load a predetermined value.
