The alloy member includes a base member constituted by an alloy material containing chromium, a chromium oxide layer for covering at least a portion of a surface of the base member, a pore that is formed in an interface region of the base member that is located 30 m or less from an interface between the chromium oxide layer and the base member, and an extending portion extending from the pore into the base member. The pore is configured to inhibit separation of the chromium oxide layer from the base member The extending portion contains an oxide of an element whose equilibrium oxygen pressure is lower than that of a major element of the base member.

An electrically-conductive member having sufficient corrosion resistivity even when the electrically-conductive member is exposed to high potential environment and a method of manufacturing the electrically-conductive member are offered.

An anode of a fuel cell has an anoe current collector defining an inlet configured to receive fuel gas and an outlet configured to output the fuel gas, a barrier that divides an active area of the anode current collector into a first area and a second area, and a flow passage configured to allow a flow of fuel gas from the inlet through the first area and the second area to the outlet. An obstacle is located in the flow passage in an inactive area of the anode current collector and is configured to change a flow direction of the fuel gas in the flow passage from the first area to the second area to achieve intra-cell mixing of the fuel gas.
