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： A fuel cell system 100 includes a fuel cell 10 and a controller 20 that controls a voltage of the fuel cell 10. The controller 20 sets a target increase amount ΔV, based on a target voltage which is a target value of voltage relative to a predetermined electric current of the fuel cell 10. The controller 20 sets a processing condition of a temporary voltage drop process, based on the target increase amount ΔV. The controller 20 performs a temporary voltage drop process under the set processing condition. The temporary voltage drop process temporarily drops the voltage of the fuel cell 10 based on a power generation characteristic of the fuel cell 10, so as to cause a temporary increase in electric current of the fuel cell 10 and change the power generation characteristic of the fuel cell 10.
