The present invention relates to an improved metal supported solid oxide fuel cell unit, fuel cell stacks, fuel cell stack assemblies, and methods of manufacture.

In a fuel cell system, a stack case which stores a stack body of power generation cells and an auxiliary device case are separated by a partition wall. An outer periphery of at least one end fluid passage provided at least at the uppermost position, among the fluid passages of the stack body, has an adjacent outer peripheral portion provided adjacent to an outer marginal portion of the stack body. The partition wall includes a facing portion. The facing portion faces an area that lies between the adjacent outer peripheral portion and the stack case and outside the outer marginal portion. At least part of a ventilation connection port configured to connect the inside of the stack case with the inside of the auxiliary device case is provided in the facing portion. The ventilation connection port has a curved shape formed along the adjacent outer peripheral portion.

A fuel cell system includes a stack case and an auxiliary device case. The stack case stores a stack including a power generation cell stack body including a plurality of power generation cells stacked horizontally in a stacking direction, and an insulating plate stacked at an end of the power generation cell stack body in the stacking direction. The auxiliary device case stores a fuel cell auxiliary device. The inside of the stack case and the inside of the auxiliary device case that are adjacent to each other in the stacking direction are separated by a partition wall. The partition wall has ventilation connection ports. The ventilation connection ports connect the inside of the stack case with the inside of the auxiliary device case. The insulating plate provided closer to the partition wall, than the power generation cell stack body, inside the stack case faces the ventilation connection ports.

A deployment device involving a frame and a deployment mechanism operably coupled with the frame and configured to perform at least one of deploy and retract a plurality of surface benthic microbial fuel cell systems in at least one manner of manually, autonomously, and semi-autonomously.
