FUEL CELL

[Problem] To provide a fuel battery cell that can prevent a bonded region between a membrane electrode assembly and a frame from breaking even when surface pressure acts on the membrane electrode assembly of which the periphery is held in the frame. [Means For Solving Problem] A fuel battery cell (1) has a membrane electrode assembly (10), a frame (20), a pair of separators (30), and support members (40). The membrane electrode assembly is formed with an anode (12) and a cathode (13) bonded so as to face an electrolyte membrane (11). The frame holds the periphery of the membrane electrode assembly. The pair of separators sandwich the frame holding the membrane electrode assembly. The support members protrude along an edge part of the frame so as to pass beyond the frame and support the membrane electrode assembly.
