Claim Text:
1. A bipolar plate, configured for a cathode and an anode to be formed on two opposite sides thereof, for a fuel cell, comprising: an electrochemical reaction region comprising a first primary side and a second primary side opposite the first primary side thereof, the electrochemical reaction region further comprising a plurality of edges disposed between the first and second primary sides; and a non-electrochemical reaction region joined with the electrochemical reaction region, the non-electrochemical reaction region comprising a first primary side and a second primary side opposite the first primary side thereof, the non-electrochemical reaction region further comprising a plurality edges that join with the plurality of edges of the electrochemical reaction region, wherein, when the electrochemical reaction region and the non-electrochemical reaction region are joined together, the first primary side of the electrochemical reaction region is flush with the first primary side of the non-electrochemical reaction region and the second primary side of the electrochemical reaction region is flush with the second primary side of the non-electrochemical reaction region, and wherein each of the edges of the electrochemical reaction region comprises an indentation and each of the edges of the non-electrochemical reaction region comprises an indentation such that the electrochemical reaction region and the non-electrochemical reaction region are joined together by the indentations of the edges of the electrochemical reaction region mating with the indentations of the edges of the non-electrochemical reaction region.
