Patent ID: 8021794

Claim:
A fuel cell comprising: a cross-shaped fuel reformer; fuel cell stacks housed in a power generating reaction chamber, each of the fuel cell stacks being formed by alternately laminating power generating cells and separators, and the fuel cells being operable to generate power when supplied with reaction gases; and heat exchangers disposed around the fuel cell stacks and outwardly of the fuel stacks with respect to a center of the power generating reaction chamber, the heat exchangers including fuel heat exchangers and air heat exchangers, wherein the fuel cell stacks are disposed in the power generating reaction chamber to form an array having at least two columns and two rows, wherein the cross-shaped fuel reformer is disposed in between the mutually facing sides of the fuel cell stacks, and wherein the cross-shaped fuel reformer has wing sections extending at right angles to form a cross-shape, and the heat exchangers are located in an opposed relation to the wing sections of the fuel reformer, with the fuel cell stacks being disposed between opposing heat exchangers and wing sections.
