Abstract

The present invention provides an online activation method and activation device for a fuel cell system. The method includes obtaining the power-on time difference between the last power-off time of the fuel cell system and the current power-on time; when the power-on time difference is greater than the threshold power-on time, obtaining the The ambient atmospheric humidity within the start-up time difference; compare the ambient atmospheric humidity and the threshold humidity to obtain the first comparison result; obtain the first time when the ambient atmospheric humidity is greater than the threshold humidity; compare the first time and the start-up time difference to obtain the second comparison result; The first comparison result and the second comparison result determine whether to activate the fuel cell system. The method provided by the embodiment of the present invention checks the fuel cell system before starting the vehicle to determine whether it needs to be activated, and pre-activates the activation step, thereby improving the life of the fuel cell system stack and slowing down the life decay of the stack. And improve the driver's driving experience.

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...
