Structure of bipolar plate for direct methanol fuel cell and shape of flow path thereof and fuel cells including them직접 메탄올 연료전지용 바이폴라 플레이트의 구조 및 유로 형상, 이를 포함하는 직접 메탄올 연료전지
The present invention relates to the structure of a bipolar plate for direction methanol fuel cell, the shape of a flow path and a fuel cell including them, more particularly, to the structure of a bipolar plate for direct methanol fuel cell using a flow path with a dispersion structure not the existing serpentine type for supplying a fuel to the new bipolar plate and functioning as a collector and the shape of a flow path. According to the present invention, a fluid flow resistance is decreased and a direct reaction region of a fluid and an electrode catalyst is increased in a bipolar plate, and therefore the performance of a fuel Cell can be improved.
