STACK STRUCTURE OF FUEL CELL

摘要

PURPOSE: A stack structure of a fuel cell is provided, to allow fuel to be distributed uniformly by allowing the fuel to be directly supplied to each unit cell along a flow path without going through manifold. CONSTITUTION: The fuel cell comprises the positive electrode of stack where fuel is supplied from a fuel tank and the negative electrode of stack where air is supplied, and obtains the electromotive force by the electrochemical reaction of the fuel and the air, wherein the stack is spiral. The spiral stack comprises a plurality of unit cells(C) comprising an electrolyte membrane(103) adhered along the underface of a spiral bipolar plate(101) to form a flow path(106), a positive electrode(104) adhered to the one side of the electrolyte membrane(103) and a negative electrode(105) to the other side of the electrolyte membrane.
