FUEL CELL

摘要

A fuel cell is provided, by which a quantity of an electrochemical reaction can be suitably increased without requiring high process accuracy in forming a gas passageway of a separator, and in addition, application can be appropriately improved as a whole, through downsizing, etc. A fuel cell (1) is provided with an electrolytic film (15), an MEA (11) composed of a pair of electrodes (16) sandwiching the electrolytic film from the both sides, and a pair of separators (12), which hold the MEA (11) in between and has a gas passageway (21) formed at a position facing each electrode (16). In each electrode (16), a gas passageway (53) is formed, corresponding to the passageway (21) on the side of the separator (12) the electrode faces.
