摘要:
A fuel cell system includes a fuel supply unit for supplying fuel, an air supply unit for supplying air, and a stack for generating electric energy through an electro-chemical reaction between hydrogen supplied from the fuel supply unit and oxygen supplied from the air supply unit. The stack includes a membrane-electrode assembly and separators disposed on both sides of the membrane-electrode assembly. Each of the separators has a pathway for transferring the air or the hydrogen, and a ratio of the width to the depth of the pathway is within a range from 0.7 to 1.3.
