<P>PROBLEM TO BE SOLVED: To provide a separation plate for fuel cell, which allows water to be easily exhausted from a gas diffusion layer through a draining groove and air to be easily diffused by a gas diffusion layer, where the water is generated in a film and an electrode assembly of a fuel cell accompanying reaction for obtaining electric energy, and the air is supplied from a passage of the separation plate. <P>SOLUTION: The separation plate for fuel cell includes: a land which makes contact and couple with the gas diffusion layer of the fuel cell; and a passage which is formed in a space with each land to become a way of hydrogen or air. A plurality of draining means are formed between the land and the passage independently so that draining of water from the gas diffusion layer to the passage is smoothly performed. The draining means includes a plurality of draining holes having Venturi effect and is formed through between the land and the passage. <P>COPYRIGHT: (C)2010,JPO&INPIT |
