A power storage device includes a fuel cell (), a battery holder () and an end plate () for sandwiching and binding the fuel cell, and an interposed member () disposed between the end plate () and the fuel cell (). The battery holder () and the end plate () are made of resin, and have a positive coefficient of thermal expansion at a temperature lower than a predetermined temperature. The interposed member () is formed to have a substantially negative coefficient of thermal expansion at a temperature lower than the predetermined temperature.

Power storage device usable at low temperatures

A conductive carbon carrier for a fuel cell having at least a surface layer graphitized, characterized in that the dimension (La) in a six-membered ring face (carbon plane) direction of a crystallite measured by X-ray diffraction is 4.5 nm or more. This carbon carrier improves the durability in a fuel cell and enables operation for a long period of time.

A lithium ion battery before pre-doping includes: a negative electrode member before initial charge having a negative active material before initial charge; a positive electrode member; an electrolyte body; a battery case; and a lithium ion supply body formed by a lithium compound capable of emitting lithium ions when positive voltage is applied to it. The lithium ion supply body is arranged so that it is at least partially in contact with the inner exposed surface of the battery case. The negative electrode member before pre-doping is electrically insulated from the metal case member. The lithium ion supply body and the negative active material before initial charge are respectively in contact with the electrolyte body.
