Integrated hydrogen fuel power system and electric bicycle

The invention discloses an integrated hydrogen fuel power system and a power-assisted bicycle, and the integrated hydrogen fuel power system comprises a shell, and a fuel cell, a hydrogen storage device and a fan which are arranged in the shell; an air inlet and an air outlet are formed in the shell; the fan guides air to flow from the air inlet to the air outlet, and the air passes through the fuel cell and the hydrogen storage device in sequence; and the hydrogen storage device is communicated with the fuel cell through a hydrogen pipeline. The integrated hydrogen storage device adopts an integrated structure and has the advantage of compact structure, and meanwhile, air is guided by the fan to flow from the air inlet to the air outlet and sequentially passes through the fuel cell and the hydrogen storage device, so that heat energy generated by the fuel cell is used for heating the hydrogen storage device, energy reutilization is realized, and the hydrogen desorption performance of the hydrogen storage dev
