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.

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： A separator has a concavo-convex structure formed in mutually reversed shapes on two opposite sides thereof to define flow paths of different fluids on the respective two sides. The concavo-convex structure includes multiple first projections formed and protruded on one side of the two opposite sides and arranged at intervals having a preset regularity. The concavo-convex structure also includes multiple second projections formed and protruded on the other side of the two opposite sides in a specific area corresponding to an area for formation of the multiple first projections on the one side and arranged at intervals having a preset regularity. The concavo-convex structure further includes reinforcing elements protruded on the one side. Each of the reinforcing elements is formed as a convex in a specific shape of connecting multiple positions where the first projections are expected to be formed according to the preset regularity, while avoiding positions corresponding to the second projections formed on the other side. This arrangement effectively prevents a potential trouble caused by deformation of the separator due to a pressure difference between the flow pressures of the respective fluids flowing on the respective sides of the separator.

摘要： A fuel cell system determines whether an operation condition of a fuel cell corresponds to a fuel gas shortage or an oxidation gas shortage. Upon determining that the fuel gas is in shortage, the system sets a lower voltage limit to be higher than that set when the system determines that the oxidation gas is in shortage. The system further controls an output voltage from the fuel cell so as to prevent output voltage from the fuel cell from decreasing below the lower voltage limit.

摘要： An improved fuel cell makes uniform partial gas pressure of a fuel gas flowing through a gas passage formed between an electrode and a separator of a fuel cell, activating an electrode reaction in a whole region of the electrode surface along the gas passage. The inlet and outlet for the fuel gas are disposed on a diagonal line of the separator to define a gas passage such that fuel gas smoothly flows even though portions of the passage away from the diagonal line. This may reduce the separator size and improve the volumetric efficiency of the fuel cell and the diffusibility of fuel gas as well as the drainage of water produced by the electrode reaction.
