A fuel cell stack device including: a first manifold 2a for supplying fuel gas supplied from a reformer 12 to a plurality of fuel cells provided in a first cell stack from above, the first manifold being connected to upper ends of the plurality of fuel cells provided in the first cell stack 10a; and a second manifold 2b for recovering fuel gas discharged from the first cell stack, and supplying the recovered fuel gas to the plurality of fuel cells provided in the second cell stack from below, the second manifold being connected to lower ends of the plurality of fuel cells provided in the second cell stack 10b.

A flow battery includes: a first liquid containing dissolved therein a condensed aromatic compound and lithium; a first electrode immersed in the first liquid; and a first circulator including a first container and a first passage prevention member. The first liquid containing the condensed aromatic compound dissolved therein has the property of causing the lithium to release solvated electrons and dissolve as cations. When the lithium dissolved in the first liquid precipitates on the first electrode, lithium precipitate particles are generated. The first circulator circulates the first liquid between the first electrode and the first container. The first circulator transfers the lithium precipitate particles generated on the first electrode to the first container. The first passage prevention member is disposed in a channel through which the first liquid flows from the first container to the first electrode. The first passage prevention member prevents passage of the lithium precipitate particles.

A reaction cell for a flow battery having flow channels positioned within a recess of a non-porous and non-brittle housing that is also a dielectric. Positioning the flow channels within the recess eliminates the need for end plates, gaskets, and insulators of conventional designs. A current collector and an electrode within the recess have areas approximately equal to the area of the recess such that they fit within the recess and maximize the contact area between them.

An elastomeric cell frame forming a unit cell of a fuel cell stack may include an insert in which a membrane electrode assembly and a pair of gas diffusion layers are bonded to each other; and an elastomeric frame disposed to surround a periphery of side surfaces of the insert, in which the side surfaces of the insert are positioned between the upper and lower surfaces of the insert, one of upper and lower surfaces of the insert and side surfaces of the insert and bonded with the periphery of the surface of the insert and the side surfaces of the insert into an integrated structure by thermal bonding.
