Abstract
A stacked fuel cell has a plurality of cell plaques, each plaque having a plurality of horizontally disposed fuel cells placed in an insulating frame. By utilizing a plurality of cell plaques, overall fuel cell stack voltage can be substantially increased by interconnecting adjacent plaque cells to form substacks which are in turn connected in series. Thus stack voltage is increased without requiring additional fuel cell height.
