Abstract
(EN)
The hydrogen gas supplier of an embodiment of the present invention is characterized in being provided with: a compressor, which compresses hydrogen gas and feeds the compressed hydrogen gas toward an accumulator that accumulates the hydrogen gas; a first adsorption tower, which is disposed between the discharge port of the compressor and the accumulator and in which a first adsorbent for adsorbing impurities in the hydrogen gas discharged from the compressor is disposed; a first valve, which is disposed between the discharge port of the compressor and the gas inlet of the first adsorption tower; a second valve, which is disposed between the gas outlet of the first adsorption tower and the accumulator; return piping, which branches between the first valve and the gas inlet of the adsorption tower and connects to the intake side of the compressor; a second adsorption tower, which is disposed partway in the return piping and in which a second adsorbent for adsorbing impurities in the hydrogen gas discharged from the compressor is disposed; and a third valve, which is disposed partway in the return piping between the gas inlet of the first adsorption tower and the gas inlet of the second adsorption tower.
