METHOD, DEVICE AND SYSTEM FOR CONTROLLING FUEL CELLS AND RAIL VEHICLE

Document Type and Number:

WIPO Patent Application WO/2018/099211

Kind Code:

A1

Abstract:

A method, device and system for controlling fuel cells, and a rail vehicle. The method comprises: detecting the operation power of a target object, the target object being powered by at least two fuel cells (S102); and in the case of detecting that the operation power of the target object is lower than a predetermined power, turning off at least one fuel cell or turning off a cell module in any one or more fuel cells on the basis of the gas conversion range corresponding to the fuel cells (S104), the gas conversion range being an output power range of fuel cells corresponding to a preset range that the hydrogen conversion rate of the fuel cells reaches. The method resolves the technical problem in the prior art of low hydrogen conversion rate of fuel cells in the case of low power of electric equipment caused by the fact that the automatic control cannot be implemented on a plurality of fuel cells according to the operation power of the electric equipment.
