METHOD FOR DETERMINING THE FLOW RATE OF REACTANTS IN EACH CELL OF AN ELECTROCHEMICAL CELL STACK |
摘要 |
Method for determining the utilisation of a reactant at the anode side or cathode side of a fuel cell. To this end a low flow with high utilisation is applied at the side to be measured and an appreciable flow with low utilisation 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 utilisation of the reactant to be measured is incorporated. Cell voltage is then measured at the outlet and is equated to the Nernst voltage. The utilisation can be determined from the table. This method can be used for determination of the flow rate and the flow distribution in a stack of electrochemical cells. |
