PURPOSE: A bipolar plate is provided to remarkably reduce manufacturing time and cost, and to improve electricity conversion efficiency by manufacturing a high-voltage stack from reduced number of stacked cells. CONSTITUTION: A bipolar plate(10), which is formed on both sides of a membrane/electrode assembly, supplying hydrogen and oxygen gas to an electrode of the membrane/electrode assembly comprises a plurality of unit plates(12) consisting of conductive material; a separation member(14) consisting of non-conductive material electrically insulting between respective unit plates; and a flow channel, which is connect-formed in the respective unit plates arranged in same plane and the separation member, supplying and exhausting gas. |
