Fuel cell coupling with hydrogen storing unit

Abstract

The present invention discloses a fuel cell of a coupling hydrogen storage unit. The fuel cell monomer comprises a cathode flow field board, an anode flow field board, a membrane electrode and a hydrogen storing unit. The fuel cell of the coupling hydrogen storage unit is formed by the superposition and coupling of the structure, utilizing the property that the hydrogen storing unit release hydrogen to absorb heat and the fuel cell reacts to disperse heat, the coupling of the heat content management of the fuel cell and the hydrogen storing unit are realized. The present invention also enables the hydrogen and air flow passage to be processed and enables the structure of the fuel cell monomer to become much simpler. While solving the problem of heat management of the hydrogen storing unit and the fuel cell, the present invention also can reduce the volume and power consumption of the system of the fuel cell as well as improve the energy density. The fuel cell disclosed in the present invention can be applied in various fields such as power supplies of electronic devices, diverse continuous power systems and the engine systems of motorcars, etc.

Description

AI Technical Summary

Problems solved by technology

In the public literature that can be seen so far, the thermal management of the fuel cell and the hydrogen storage unit are considered separately, which is not conducive to reducing the internal power consumption of the fuel cell system, improving efficiency, and is not conducive to improving the performance and performance of the fuel cell. life

Moreover, the hydrogen storage unit and the fuel cell of such a system are separated, and the energy density of the system is not high
