FIELD: electrochemical fuel cells; method and device for assembling plurality of fuel-cell plates to form fuel stack.
SUBSTANCE: proposed fuel cell compressive subassembly designed to apply compressive force to fuel stack by means of fixed frame wherein fuel cell can be directly built and to maintain this force has frame assembly incorporating at least two opposing side walls spaced apart at certain distance with aid of base member passed between them in bottom position on sides; opposing side walls and base member form seats to receive fuel-cell plates; each opposing side wall is provided with at least one catching member on internal wall designed to engage top member of cover that forms top part of frame assembly. Cover member functions to close frame assembly and to apply pressure to plates installed therein by means of automatically locking jointing with seat in definite position in first direction which is actually orthogonal to surface of plates.
EFFECT: facilitated assembling procedure affording precise alignment of plates and their uniform compression throughout entire surface area as well as ability of pre- and post-assembly maintenance of this compression.
