The invention provides an online activation method and an activation device for a fuel cell system. The method comprises the following steps that: a start-up time difference between last shutdown time and current start-up time of the fuel cell system is acquired; when the start-up time difference is greater than a threshold start-up time, the ambient atmosphere humidity of the fuel cell system within the start-up time difference is acquired ; the ambient atmosphere humidity is compared with the threshold humidity to obtain a first comparison result; a first time when the ambient atmosphere humidity is greater than the threshold humidity is acquired; the first time is compared with the start-up time difference to obtain a second comparison result; and whether the fuel cell system is to be activated is determined according to the first comparison result and the second comparison result. According to the method provided by the embodiment of the invention, the fuel cell system is checked before a vehicle is started, whether the fuel cell system needs to be activated or not is judged, and the activation step is preposed, so that the service life of the fuel cell stack of the fuel cell system is prolonged, the service life attenuation of the fuel cell stack is slowed down, and the driving experience feeling of a driver is improved.
Description
technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to an online activation method and an activation device for a fuel cell system. Background technique [0002] Fuel cell vehicles are new energy vehicles with broad development prospects, which have many advantages such as short hydrogen refueling time and long driving range. Fuel cell systems usually include fuel cell stacks and peripheral hydrogen, air, cooling and other component systems. Fuel cell stacks include proton exchange membranes, catalyst layers, gas diffusion layers, bipolar plates, etc., where proton exchange membranes need It maintains good performance under humidity. If it is too dry, it will lead to an increase in proton conduction resistance and a decrease in performance. In actual use, fuel cell vehicles will inevitably have a long standing process, resulting in the loss of water vapor bound to the proton exchange membrane during the standing proces...
