Estimating the term…
The present invention provides a fuel cell stack with a water drainage structure, which can effectively drain condensed water and prevent water from flowing into unit cells by combining an end anode plate (EAP) and an end cathode plate (ECP), which are formed by modifying an anode plate (AP) and cathode plate (CP) respectively. In doing so, the modified anode plate (AP) and cathode plate (CP) are converted into a dummy cell which is positioned at the end portions of the fuel cell stack.
A fuel cell stack having a water drainage structure, the fuel cell stack comprising a plurality of unit cells disposed between end plates at both ends of the fuel cell stack respectively, wherein at least one cathode dummy cell and at least one anode dummy cell are included in the fuel cell stack, the at least one cathode dummy cell and the at least one anode dummy cell provided for draining water from the fuel cell stack and are disposed between end cells of a power generation unit and the end plates at both ends of the fuel cell stack.
