A fuel-cell-equipped apparatus includes a fuel cell unit that includes a fuel cell module and a fuel cell case. The fuel cell module includes cells stacked on each other and is housed in the fuel cell case. A pipe is provided at one side of the fuel cell module in the direction in which the cells are stacked. The fuel cell unit is supported on a base via supporting members (mounting insulators), at two points at the side where the pipe is provided or the side closest to a gravity center of the fuel cell unit and at one point in the opposite side.

The number of assembling steps of a fuel cell module is reduced. Moreover, permeating of moisture from the outside is suppressed. To realize this, a fuel cell module of the present invention includes a fuel cell having a structure in which both ends of a cell laminate in a laminating direction of cells are held by end plates, a fuel cell case in which the fuel cell is received, and a plurality of holding portions which hold the fuel cell via the end plates. Each holding portion includes a first fastening member having a part thereof bonded to the end plate, a mount member interposed between the first fastening member and the fuel cell case, and a second fastening member which fastens the mount member and the fuel cell case, and the fuel cell case is provided with a protrusion part having such a shape as to cover the part of the first fastening member while avoiding interference with the part.

Fuel cell module

A fuel cell () includes a lamination () of a plurality of unit cells (), current collector plates () arranged at both ends of the lamination (), end platesrespectively provided outside the current collector plates () with 5 insulating plates () interposed therebetween, and fastening members () for fastening the end plates () in the laminating direction to apply desired pressing force to the lamination (). A barcode () corresponding to particular information relating to a unit cell () is provided on the exposed side surface of a separator () of the unit cell (). According to this fuel cell (), the barcodecan be easily read requiring no disassembly of the fuel cell (). Moreover, as the information relating to the fuel cell can be obtained from the barcode (), the information that cannot be determined from outer appearance can be obtained, resulting in improved service operations.

Fuel cell component having a retrieval code

A fuel cell separator is pressed so that one side thereof defines a gas flow channel and that the other side thereof defines a coolant flow channel. A width dand a cross-sectional area Sof the gas flow channel and a width dand a cross-sectional area Sof the coolant flow channel satisfy a relationship: d&#x2267;dor a relationship: S&#x2267;S.
