| 摘要 |
The invention relates to a fuel cell system comprising: - a stack of electrochemical cells (10) separated by bipolar plates, each of the cells comprising an anode, a cathode and an ion exchange membrane, - a fuel gas supply circuit and an oxidant gas supply circuit, and - a coolant circuit for circulating a liquid coolant, the coolant circuit comprising a secondary circuit and a primary circuit smaller than the secondary circuit, the primary and secondary circuits being isolated from each other by a thermostatic valve (2), - a micropump (6) mounted at the outlet of the stack and allowing the volume of water inside the stack to be agitated, the system further comprising means for determining an inner temperature of the core of the stack, and means for activating the primary coolant circuit when the inner temperature exceeds a predetermined threshold. |
