Patent ID: 7416805

Claim:
A fuel cell device, comprising: a case including: a holder frame; a first hemi-case movably attached to a first open side of the holder frame; and a second hemi-case movably attached to a second open side of the holder frame opposite to the first side, the first hemi-case and the second hemi-case being movable in an approaching direction in which the first hemi-case and the second hemi-case approach up to a close position, and a separating direction in which the first hemi-case and the second hemi-case separate in open positions; a fuel cell unit in the case, including a plurality of fuel cells movably arranged inside the holder frame; and a springy member that exerts a force between two adjacent cells to increase a distance therebetween; wherein when the first hemi-case and the second hemi-case are moved in the separating direction, the two adjacent fuel cells are moved by the springy member, thereby increasing the distance between adjacent two of the fuel cells.
