The terminal structure includes an electric wire including a core wire and a terminal member attached to the electric wire. The terminal member includes a joining portion to which the core wire is joined and the sealing portion surrounding the joining portion and including an opening portion having the joining portion exposed therethrough. The core wire is joined to the joining portion through the opening portion and is in close contact with the sealing portion annularly around the opening portion.

Terminal structure

A wire harness includes a first electric wire member including a first flexible wire and a hard wire electrically connected to the first flexible wire, a second electric wire member including a second flexible wire, and a tubular member through which the first and second electric wire members extend. The wire harness also includes a tubular holder that is attached to a longitudinal end portion of the tubular member and holds the first and second electric wire members therein. The holder has a first housing recess that is located in an inner surface of the holder and houses the second electric wire member.

Wire harness

A low-temperature startup method for a fuel cell, includes detecting a temperature of the fuel cell. It is determined whether the temperature is lower than a threshold temperature. A drying operation to dry the fuel cell is increased when the temperature is determined to be lower than the threshold temperature upon starting the fuel cell to generate electric power via an electrochemical reaction between fuel gas and oxidant gas.

Low-temperature startup method for fuel cell system

A fuel cell stack includes a stacked body, a first insulator, and a first shim. The stacked body includes electrolyte-electrode assemblies and separators. The electrolyte-electrode assemblies are stacked in a stacking direction and have a first end electrolyte-electrode assembly disposed at a first end of the stacked body. The separators includes a first end separator disposed at the first end of the stacked body between the first end electrolyte-electrode assembly and a first contact end plate having a first contact surface which the first end separator contacts. The first shim is provided in a first recess between the first contact end plate and the first insulator and has a thickness such that an outer peripheral surface of the first end separator is positioned between the first contact surface of the first contact end plate and an outer peripheral surface of the first insulator in the stacking direction.

Fuel cell stack

Provided is a fuel cell including a plurality of stacked unit cells, each including a membrane-electrode assembly and a separator stacked on the membrane-electrode assembly. The separator includes a separator plate that overlaps the membrane-electrode assembly when seen from a stacking direction, a first terminal portion configured to protrude from the separator plate toward an outer side in a plane direction, a plate covering portion configured to cover an outer peripheral edge of the separator plate, and a terminal covering portion configured to be formed integrally with the plate covering portion and covers the first terminal portion. A plurality of the first terminal portions, which are adjacent to each other in the stacking direction, include offset portions which shift from each other when seen from the stacking direction, and are covered with the terminal covering portion.
