An improved heat-insulating support device is disclosed which is capable of supporting a coolant tank to a vacuum vessel in a manner such that when the vacuum tank is subjected to a great external force after the coolant tank has been cooled down to a cryogenic temperature, the coolant tank and hence cryogenic equipment mounted thereon are held in place and prevented from being displaced beyond a prescribed allowable range, without impairing the intended heat-insulating capability thereof. The heat-insulating support device comprises a heat insulating support member disposed outside the coolant tank with one end connected with the coolant tank; a mounting rod having one end connected with the heat-insulating support member and its other end projected outwardly through the vacuum vessel; and a spring for resiliently mounting the other projected end portion of the mounting rod on the vacuum vessel, the spring having a non-linear spring characteristic including a small spring constant for mainly absorbing thermal contraction of the coolant tank and a large spring constant for mainly suppressing displacement of the coolant tank due to large external forces acting thereon after the thermal contraction of the coolant tank.

A fuel cell comprises a gas separator having a dense layer, with porous portions disposed on both faces of the dense layer. The fuel cell, therefore, can store excess electrolyte, and absorb volume changes in the electrolyte without accompanying 'flooding'. Further, the fuel cell can reduce the thickness of a unit cell, and improve the space factor to output of the fuel cell.
