PURPOSE: A method for determining the utilization of a reactant at the anode side or cathode side of a fuel cell is disclosed. CONSTITUTION: To this end a low flow with high utilization is applied at the side to be measured and an appreciable flow with low utilization is applied at the other side. A table is compiled in which the relationship between the Nernst voltage under the outlet conditions, such as the temperature, and the utilization of the reactant to be measured is incorporated. Cell voltage is then measured at the outlet and is equated to the Nernst voltage. The utilization can be determined from the table. The method can be used for determination of the flow rate and the flow distribution in a stack of electrochemical cells. |
