Switch-off method for fuel cell system involves varying parameters of working materials fed to fuel cell so fuel cell dries, stopping dosing of anode side materials then cathode side materials

摘要

The method involves varying the operating parameters of working materials fed to the fuel cell (3) so that the fuel cell dries, then interrupting dosing of anode (5) side working materials, then, as soon as there is no working material in the anode region, interrupting the dosing of cathode side working materials.
