Title:
GAS SUPPLY CONTROL METHOD, DEVICE AND SYSTEM OF FUEL CELL, AND RAILWAY VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/219058
Kind Code:
A1
Abstract:
Disclosed in the present invention are a gas supply control method, device and system of a fuel cell, and a railway vehicle. The method comprises: continuously inputting a reaction gas to a fuel cell on the basis of a preset excess coefficient, wherein the preset excess coefficient is greater than a standard excess coefficient; when the work power of a target object is increased, detecting in real time or regularly whether the current excess coefficient is less than or equal to the standard excess coefficient; and if the detected excess coefficient is less than or equal to the standard excess coefficient, rising the current excess coefficient to the preset excess coefficient. The present invention solves the technical problem of a slow response speed of an existing fuel cell when the electricity consumption demand is increased.
