ABSTRACT:
An elongated multi-layered structure including multiple symmetrical two-sided fuel cells is made by a low-cost continuous process. Each cell assembly derived from the structure comprises two basis cells having a common positive electrode. By rolling each cell assembly into a spiral, a compact package having two cells connected in parallel and characterized by a relatively large current capabilty is realized. In the spiral package, conductive corrugations are utilized between adjacent surfaces of the rolled assembly to ensure that a fuel/oxidizer mixture can access permeable electrodes formed on the respective surfaces of the assembly.
