Use of a fuel cell unit in which a reaction gas (H2 or O2) is fed to a fuel cell stack (2A,B,C) a specific amount (G) of the reaction gas stream is decomposed by the electrolytic reaction as a result of which the reaction fluid accumulates (sic, anfallen), and the stream level produced in the fuel cell unit over a time interval (delta T) serves as a measure for the quantity of gas stream (mG) produced in a time (delta T), and the amount of fluid accumulated (sic) in this time interval. An independent claim is included for a fuel cell unit including a control unit (20) for controlling valves (10,14) in relation to the accumulated amount of fluid. |
