摘要： In a fuel cell system, a controller is programmed to control a first gas supply mechanism to deliver a first gas containing a fuel gas to a cathode in a pre-stop process performed at a system stop of the fuel cell system. The controller is programmed to control the first gas supply mechanism to stop the delivery of the first gas in a first state where a partial pressure difference between an anode and the cathode with respect to at least the fuel gas of remaining gases in the anode and in the cathode is reduced to or below a preset reference value.

摘要： A fuel cell system having a fuel cell includes a power generation-time gas supplier that supplies hydrogen-containing fuel gas to an anode of the fuel cell and supplies an oxygen-containing oxidizing gas to a cathode of the fuel cell during power generation of the fuel cell. The fuel cell system also includes an anode potential rise information acquirer that acquires anode potential rise information, which represents information regarding a status of an anode potential rise of the fuel cell, after termination of supplies of the fuel gas and the oxidizing gas by the power generation-time gas supplier. The fuel cell system further includes an anode morphology variation deriver that derives an anode morphology variation representing a degree of a morphology change of a catalyst metal included in the anode, based on the anode potential rise information.

摘要： A fuel cell system of the present invention can suppress an excessively wet or dry state of a fuel cell stack so as to thereby ensure the durability of the fuel cell stack. The fuel cell system supplies an oxidant gas with a reduced flow rate per unit time and for a long time period if the rate of voltage decrease of the stack becomes faster than a threshold rate, and supplies the oxidant gas with an increased flow rate per unit time and for a short time period if the rate of voltage decrease becomes slower than a threshold rate.
