To compact a hydrogen storage vessel and improve its heat exchange efficiency and hydrogen absorption and desorption performance.
Heat exchanger cores 1 provided with one hydrogen absorption alloy storage layer 10 and one heat medium flow passage layer 9 between each plate by laminating a plurality of plates 2, 2 are arranged in parallel and mutually with a clearance 26 therebetween so as to oppose and expose one end parts of the hydrogen absorption alloy storage layer, external shell plates 20, 21, 22 are fixed to outer faces of the heat exchanger cores 1 so as to block the clearance between the plates and the clearance between the cores, and a hydrogen communication port 22c communicating with the clearance 26 and a heat medium inflow port 15a and a heat medium outflow port 16a communicating with the heat medium flow passage layer are provided in the external shell plates 20, 21, 22. The heat exchanger cores 1 are assembled by primary brazing, a plurality of heat exchanger cores are arranged in parallel and mutually with the clearance therebetween, and the external shell plates are arranged on the outer faces of the heat exchanger cores and are assembled by secondary brazing.
