    摘要: A fuel cell system of the present invention includes: a fuel cell (1) supplied with fuel gas and oxidizing gas to generate electricity; a fuel gas supply unit supplying the fuel gas to the fuel cell (1); an oxidizing gas supply unit supplying the oxidizing gas to the fuel cell (1); an aftercooler (7) cooling the oxidizing gas supplied to the fuel cell (1) by heat exchange with a coolant; an oxidizing gas temperature detector (16, 17) detecting temperature of the oxidizing gas; and a coolant circulation controller (21a) starting circulation of the coolant when the detected temperature of the oxidizing gas exceeds a predetermined value. The predetermined value is set to a value of not higher than a minimum electricity generation temperature of the fuel cell (1), and a circulation timing and flow rate of the coolant for the aftercooler (7) are controlled such that the supplied oxidizing gas does not become cold. This enables the fuel cell (1) to generate electricity at cold start-up.

    摘要: A fuel cell system having a fuel cell for causing reactant gas to be electrochemically reacted to generate power, a reactant gas supply path for supplying reactant gas to the fuel cell, a reactant gas recirculation path for recirculating exhaust gas discharged from the fuel cell and combining the recirculating exhaust gas with reactant gas flowing through the reactant gas supply path to the fuel cell, and a pump unit disposed in the reactant gas recirculation path to pump the recirculating exhaust gas through the reactant gas recirculation path. A pump-tempering apparatus increases the temperature of the pump unit and a controller controls the pump-tempering apparatus. After the controller receives a fuel cell system stop signal, the controller controls the pump-tempering apparatus such that the temperature of the pump unit becomes higher than the temperature of piping in the reactant gas recirculation path.

    摘要: An analysis method and analysis apparatus involve analysis for a sulfur component using ultraviolet fluorescence capable of removing the interferential influence of NO with good efficiency and certainty to thereby measure a concentration of only sulfur components such as SO2 and others even in continuous measurement over a long term with a high precision. An analysis method involves analysis for a sulfur component using ultraviolet fluorescence. A sample gas is illuminated with ultraviolet and fluorescence is emitted by the ultraviolet illumination and detected to measure concentrations of sulfur components including at least SO2 in the sample gas. NO, which is an interferential component in the sample gas, is oxidized to nitrogen dioxide, followed by the illuminating of the sample gas with ultraviolet.
