Fig. 1: Metal-based monolithic stack design.
From: Production of a monolithic fuel cell stack with high power density
a Illustrations of conventional and monolith fuel cell stacks with five repeat units and a single repeating unit (SRU) monolith stack. The numbers 1, 2, and 3 correspond to the interconnects, fuel cells (electrolyte and electrodes), and cell supports, respectively. b Photograph of three modules of SRU monolith. c Illustration of an exploded view of a SRU monolith. The numbers 4, 5, 6, and 7 correspond to interconnects and gas distribution channels (400 µm thick including 250 µm high gas channels), electrodes (10 µm), electrolyte (10 µm), and sealing (10 µm), respectively. d Enlarged cross-sectional view of a SRU monolith (for clarity, the scale of the layers thickness is not respected).
