Abstract
Proposed is a fuel cell separator. More particularly, proposed is a fuel cell separator having a point contact channel structure, in which the channel structure of the separator is formed inclinedly to ensure smooth transfer and discharge of condensed water, and an overlapping portion of opposite anode separator and cathode separator forms a point contact to have a minimum area so that water accumulation caused by a pressed gas diffusion layer and electrode performance degradation can be minimized.
Claims5
A fuel cell separator having a point contact channel structure, the fuel cell separator comprising:
- a pair of an anode separator and a cathode separator that are formed on opposite sides of a membrane electrode assembly to form a passage for flow of fuel and a passage for flow of air, respectively,
- wherein the anode separator comprises a plurality of first channels protruding toward the membrane electrode assembly and spaced apart from each other at regular intervals to form a plurality of passages for flow of the fuel,
- and the cathode separator comprises a plurality of second channels protruding toward the membrane electrode assembly and spaced apart from each other at regular intervals to form a plurality of passages for flow of the air,
- wherein the first channels and the second channels are formed to be inclined at a predetermined angle along a longitudinal direction of an electrode, and are formed to be inclined at different angles to make point contact.
