The present invention provides a sealing structure for a bipolar plate of a fuel cell. The sealing structure includes a plurality of bipolar plates and a gas guidance and reaction layer. A gas channel is placed laterally onto the bipolar plate corresponding to the gas guidance and reaction layer. A gasket is located between a bipolar plate and the gas guidance and reaction layer. A permeable portion is formed on the gasket corresponding to the gas channel. A concave surface is placed laterally on the bipolar plate corresponding to the gas guidance and reaction layer for mating with the gasket. When the bipolar plate, gas guidance and reaction layer and gasket are fastened, the deformation amount of the gasket is accurately controlled through the height limitation of the concave surface.
