Abstract: Disclosed are a separator for fuel cells capable of minimizing the volume of a system and the use of sealants, and a stack for fuel cells, more particularly, a stack for solid oxide fuel cells, including the same. Specifically, by adding a metal sheet having a specific shape, position and size to the separator, the stress applied to the sealant can be uniformized, and thus the oxidizing agent and fuel can be separated and electrically isolated using only a piece of sealant. Therefore, the stack for fuel cells is characterized in that there is no variation in temperature, reactant concentration, power, or the like between respective unit cells, so delamination and microcracks do not occur, the volume is minimized, and the power density per unit volume is very high.

Abstract: Disclosed herein are a fuel cell manifold and a fuel cell stack including the same. The manifold may include a cover plate, an air guide plate configured to guide a flow of air in the manifold, a fuel guide plate configured to guide a flow of fuel in the manifold, and an auxiliary plate providing a passage for inflow of air and outflow of fuel.
