Patent ID: 7402354

Claim:
A fuel cell apparatus comprising: a fuel cell including an electrolyte membrane, a fuel electrode provided on one side of the electrolyte membrane and to which a fuel-containing material is supplied, and an air electrode provided on the other side of the electrolyte membrane and to which air is supplied; a fuel cell cooling system for cooling the fuel cell by supplying a fuel cell cooling water to the fuel cell; a hot water storage unit for supplying water for recovering heat generated upon operation of the fuel cell through heat exchange; and a heat exchange unit including a laminated structure, a water entrance provided at the laminated structure and through which the water from the hot water storage unit flows into the laminated structure, and a water exit provided at the laminated structure and through which the water from the hot water storage unit is discharged out of the laminated structure after the water passes through the laminated structure; wherein the laminated structure of the heat exchange unit is integrally formed into lamination by a heat exchanger for the fuel cell cooling water for recovering heat in the fuel cell cooling water of the fuel cell cooling system and (i) a first heat exchanger for eliminating moisture contained in the fuel-containing material to be supplied to the fuel cell for power generation through the heat exchange unit, (ii) a second heat exchanger for eliminating moisture contained in a fuel off-gas discharged from the fuel cell after the power generation through the heat exchange unit, and (iii) a third heat exchanger for eliminating moisture contained in an air off-gas discharged from the fuel cell after the power generation through the heat exchange unit.
