Abstract

The invention relates to the technical field of a fuel cell, and discloses a method and device for activating a fuel cell stack. The method for activating the fuel cell stack comprises the steps of allowing the fuel cell stack to continuously run for 5 minutes at 300A under a certain environment; allowing the fuel cell stack to continuously run for 90 seconds at 300A under another one environment,stopping running, continuing for 30 seconds, and repeating the step until an output power is not raised or an average voltage is not raised, or repeating the step for times more than or equal to 10 times and then performing the next step; and allowing the fuel cell stack to continuously run for 90 seconds at 300A under a third environment, allowing the fuel cell stack to stop running, continuingfor 30 seconds, repeating the step if the output power is lower than a preset power or the average voltage is lower than a preset voltage, otherwise completing the performance activation of the fuel cell stack. With the method and device for activating the fuel cell stack, disclosed by the embodiment of the invention, the performance of the fuel cell stack can be rapidly activated, the activationefficiency is improved, and the activation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a method and device for activating fuel cell stacks. Background technique [0002] The fuel cell stack is a power generation device composed of multiple single cells in series, which converts the chemical energy of the fuel into electrical energy. Therefore, the fuel cell stack is not limited by the Carnot cycle effect, and the power generation efficiency In addition, the fuel cell stack has the advantages of low emission and low noise. Therefore, fuel cells are widely used in the automotive industry, energy power generation, shipbuilding industry, aerospace, household power supply and other industries. [0003] After the fuel cell stack is assembled and formed, its performance needs to be activated to ensure that the performance of the fuel cell stack reaches the best state of use. The battery stack has good performance. At present, the activation of the existing fuel cell ...
