1. A fuel cell cassette for forming a fuel cell stack along a fuel cell axis, said fuel cell cassette comprising:
a cell retainer;
a plate positioned axially to said cell retainer and defining a space axially with said cell retainer;
a fuel cell having an anode layer and a cathode layer separated by an electrolyte layer; an outer perimeter of said fuel cell being positioned in said space between said plate and said cell retainer, thereby retaining said fuel cell, said plate extending to said cell retainer such that said plate is secured to said cell retainer and such that a closed cavity is defined between and bounded by said cell retainer, said fuel cell, and said plate such that said cell retainer, said fuel cell, and said plate are walls of said closed cavity; and
a seal disposed within said closed cavity and in contact with said cell retainer, said fuel cell, and said plate for sealing the edge of said fuel cell, said seal being compliant at operational temperatures of said fuel cell, thereby allowing lateral expansion and contraction of said fuel cell within said closed cavity while maintaining sealing at the edge of said fuel cell.
