Title:
METHOD FOR DETERMINING THE DRY STATE OF AN ANODE OF A FUEL CELL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/066813
Kind Code:
A3
Abstract:
The invention relates to a method for detecting the dry state of a fuel cell system (100), in particular an anode (103), wherein the fuel cell system (100) comprises a fuel cell stack (101), an air path (10), an exhaust line (12) and a fuel line (20) with a recirculation circuit (50). During a purging and draining process, the temporal progression of the H2 concentration in the exhaust line (12) is measured and the dry state of the fuel cell system (100), in particular the anode (103), is determined by assessing the measured H2 concentration.
