Abstract:
In order to provide a step capable of reliably detecting a CO concentration in a reformed gas at low cost and a hydrogen purifier capable of fully exerting a function of a CO purifying catalyst, a gas concentration detector comprising a reaction chamber which has a catalyst layer and a gas temperature detector and capable of detecting the concentration of carbon monoxide in the gas by means of a signal of the temperature detector referring to a reformed gas passing along through the reaction chamber.
