The present invention discloses a silicon plate, a method for producing a silicon plate, an application of silicon to a fuel cell, a fuel cell stack structure, a fuel cell, and an application of a fuel cell. The silicon plate is made of a doped conductive crystalline silicon material, and has an internal cooling medium flow channel, a front reducing agent flow channel, and/or a back oxidizing agent flow channel, and each of the internal cooling medium flow channel, the front reducing agent flow channel, and/or the back oxidizing agent flow channel is provided with a silicon plate inlet-outlet combination connected to thereof. Compared with a metal plate, a graphite plate, or a composite material plate in the existing technologies, the silicon plate provided in the present invention are more advantageous in service life, costs, efficiency, and power density, and therefore significantly drives mass industrialization of fuel cells.
