摘要： A fuel cell is disclosed comprising: a power generation layer including an electrolyte membrane, and an anode and a cathode provided on respective surfaces of the electrolyte membrane; a fuel gas flow path layer located on a side of the anode of the power generation layer to supply a fuel gas to the anode while flowing the fuel gas along a flow direction of the fuel gas approximately orthogonal to a stacking direction in which respective layers of the fuel cell are stacked; and an oxidizing gas flow path layer located on a side of the cathode of the power generation layer to supply an oxidizing gas to the cathode while flowing the oxidizing gas along a flow direction of the oxidizing gas opposed to the flow direction of the fuel gas. A power generation area of the fuel cell, in which electric power is generated, has an upstream region including a most upstream position along the flow direction of the fuel gas and a downstream region including a most downstream position along the flow direction of the fuel gas. A midstream region, which is a remaining region of the power generation area other than the upstream region and the downstream region, has higher water vapor transfer resistance between the anode side and the cathode side than the upstream region and the downstream region.

摘要： The procedure of the invention successively obtains an estimated value of amount of liquid water in a fuel cell during operation in each specified period by the following steps (a) to (d), thereby improving the detection accuracy of the water condition inside the fuel cell. The step (a) obtains a previous estimated value. The step (b) obtains a drainage rate that represents an amount of liquid water discharged from the fuel cell per unit time, based on the previous estimated value and a value representing a current flow rate of a reactive gas in the fuel cell. The step (c) multiplies the drainage rate by a period of obtaining the estimated value, so as to calculate an amount of liquid water discharged from the fuel cell for a specified duration. The step (d) determines a current estimated value, based on the amount of liquid water discharged from the fuel cell for the specified duration.

摘要： When a use index (IDX) indicative of a degree of use of external charging is less than a threshold (IDXref), an electronic control unit (24, 40, 52, 70) determines that the degree of use of external charging is low, and executes (S220) a charging guide control to promote the use of external charging at the time of parking at a battery charging point, such as at home (96) or in a battery charging station 68), where the external charging is performable. Hereby, it is possible to promote a driver to use external charging at the time of parking at the battery charging point. As a result, the use of external charging can be promoted.

摘要： A fuel cell system 100 includes a fuel cell 10, a cathode gas supply system 30, a supply valve 34, an exhaust valve 43 and a controller 20. The fuel cell 10 has a supply manifold M1, an exhaust manifold M2, and a power generation area GA connected with these manifolds M1 and M2. The cathode gas supply system 30 causes a gas to be flowed into the supply manifold M1. The supply valve 34 is operable to seal the supply manifold M1, whereas the exhaust valve 43 is operable to seal the exhaust manifold M2. The controller 20 closes the supply valve 34 and the exhaust valve 43 after operation stop of the fuel cell 10 to seal the fuel cell 10 under a specified pressure and then waits for a predefined time. The controller 20 subsequently opens the supply valve 34 to move water remaining in the power generation area GA on the flow of the gas toward outside of the power generation area GA.
