Title:
燃料電池の薄膜内の漏洩箇所を検知するための方法およびシステム
Document Type and Number:
Japanese Patent JP7079351
Kind Code:
B2
Abstract:
A method for identifying a leak (4′) within a membrane (4) of a fuel cell (5) during operation of a motor vehicle, comprising the steps: reducing the power provided by the fuel cell (5) starting from an output power to a minimum value; determining measurement values of the current cell voltage of the fuel cell (5) whilst the reduced power at the minimum value is provided by the fuel cell (5); and assessing a state of the membrane (4) of the fuel cell (5) on the basis of the determined measurement values in order to identify a leak (4′). The power reduced by the fuel cell (5) whilst measurement values of the current cell voltage are determined is provided at the same level by at least one further energy source.
