| Abstract: | The hydrogen circulation pump circulates the supersaturated hydrogen from the fuel cell outlet to the inlet to realize the recycling of hydrogen and promote the internal water balance.The development status and main technical requirements of hydrogen circulation pumps were analyzed,a key index evaluation system was constructed,and a certain type of hydrogen circulation pump was used as a research object to carry out experimental verification.The results show that the pressure difference between inlet and outlet has little effect on the dynamic response time,the ambient temperature has no obvious effect on the working characteristics,and the pipeline flow resistance and salt spray test have greater influence on the working characteristics. |
