Abstract: According to one aspect of the present invention, a pressure swing adsorption (PSA) device includes an adsorption tower configured to introduce hydrogen gas and adsorb impurity components in the hydrogen gas by using a pressure swing adsorption (PSA) method, an adsorbent of one layer made of activated carbon or an adsorbent of two layers in which activated carbon and zeolite are stacked being disposed in the adsorption tower, the hydrogen gas containing carbon monoxide (CO) of 0.5 vol % or more and 6.0 vol % or less and methane (CH4) of 0.4 vol % or more and 10 vol % or less as the impurity components; and a densitometer configured to detect a concentration of CO in the hydrogen gas discharged from the adsorption tower, wherein the impurity components are adsorbed and removed to cause the CO concentration measured by the densitometer to fall below a threshold.

Abstract: A flowmeter failure determination method includes: a step of measuring a filling amount of hydrogen gas filled in a fuel tank of an automobile, using a flowmeter; a step of acquiring information of a pressure and a temperature of the fuel tank; a step of calculating the filling amount of the hydrogen gas filled in the fuel tank based on the acquired pressure and temperature and a capacity of the fuel tank in which an expansion rate of the fuel tank is considered; and a step of determining presence or absence of a failure of the flowmeter using an error value between the measured filling amount and the calculated filling amount.
