AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following defects: there is only one hydrogen storage tank, which cannot meet the power supply duration of the large-capacity power generation system, and the continuous power generation time is still limited

[0005] At the same time, online hydrogenation cannot be realized during the power generation process of the hydrogen fuel cell. When the hydrogen fuel in the hydrogen storage unit is insufficient and needs to be hydrogenated, the temperature of the gas in the hydrogen storage tank will increase during the hydrogenation process. If the hydrogen fuel cell is supplied at the same time Hydrogen will cause safety problems. Hydrogenation must be carried out after stopping power generation and power supply to loads, and then restart to continue power generation after hydrogenation. Due to the limited space of the hydrogen storage unit reserved by the hydrogen energy power generation device, when the hydrogen storage capacity is constant Under the circumstances, it is impossible to continuously supply power to the load for a long time
