Abstract: The present invention relates to a combined plate structure for a multi-slice fuel cell, which comprises a conducting substrate and a channel plate. The conducting substrate is in the form of a base, and the channel plate is in the form of a sheet having a channel therein. By assembling the conducting substrate and the channel plate together, a combined plate having a channel therein is accordingly formed such that the channel through the channel plate can be easily produced in a conventional mass manufacturing manner. The channel plate can be made of different materials based on various polarities so as to enhance corrosion resistance and electric conductivity thereof, thus lowering production cost and prolonging the service life of the fuel cell.
