A fuel cell stack device that can suppress a damage to fuel cells is provided. A fuel cell stack device includes a fuel cell stack in which a plurality of columnar fuel cells are arranged upright, and are electrically connected via a current-collecting member interposed between adjacent fuel cells, fuel cells stack-supporting members disposed so as to hold the fuel cell stack via an end current-controlling member from both end sides, and a manifold that fixes lower ends of the fuel cells, and that supplies a reactant gas to the fuel cells. The fuel cell stack-supporting member has a lower end fixed to the manifold and is an elastically deformable member, and is disposed such that a fixed portion thereof fixed to the manifold is at a same or lower level than a fixed portion of the fuel cells.

Fuel cell stack device, fuel cell stack connection device, and fuel cell device

A fuel cell assembly in which ends on one side of the cells forming gas passages are gas-tightly fixed to a holding means. Between the peripheries of the ends on one side of the cells and the holding means, there are arranged a fixing member for fixing the cells to the holding means and a sealing member for accomplishing a gas-tight sealing between the ends on one side of the cells and the holding means. The fixing member has a softening temperature of not lower than 1000&#xb0; C. and the sealing member has a softening temperature of from 700 to 1000&#xb0; C.
