  • Publication number: 20240387843
    Abstract: An ion analysis device includes a sampling unit configured to sample condensate of exhaust gas flowing through an exhaust gas line in a fuel cell; and a sensor unit configured to measure an ion concentration of the condensate, in which the sampling unit is configured to sample the condensate of the exhaust gas from a first reservoir that is provided to the exhaust gas line and where the condensate of the exhaust gas is collected, or to sample the exhaust gas from the exhaust gas line and to collect condensate of the sampled exhaust gas in a second reservoir.

  • Publication number: 20240145744
    Abstract: The present invention is a fuel cell evaluation system that obtains an actual gas consumption amount in a fuel cell in real time with accuracy and calculates a consumption amount of a fuel gas in the fuel cell, the fuel cell evaluation system including: a fuel gas supply path that supplies a fuel gas of a first flow rate to the fuel cell; a fuel gas discharge path that discharges the fuel gas from the fuel cell; an inert gas introduction path that introduces an inert gas of a second flow rate into the fuel gas discharge path or the fuel gas supply path; a first fuel gas concentration meter that measures a fuel gas concentration in a mixed gas of the fuel gas and the inert gas flowing through the fuel gas discharge path; and a fuel gas consumption amount calculation unit that calculates the consumption amount of the fuel gas in the fuel cell based on the first flow rate, the second flow rate, and the fuel gas concentration measured by the first fuel gas concentration meter.
