PROBLEM TO BE SOLVED: To provide a method for manufacturing a porous carbon electrode for a solid polymer-type fuel battery, which is high in surface smoothness.SOLUTION: A method for manufacturing a porous carbon electrode comprises the steps of: preparing a coating liquid including two kinds of carbon powder, a water-repellent agent, a surfactant and water, in which the two kinds of carbon powder consist of first carbon powder of which the average particle diameter is 0.03-10 μm, and second carbon powder of which the average particle diameter is larger than that of the first carbon powder by 0.05-10 μm; applying the coating liquid onto a base material of the porous carbon electrode to form a uniform coating film on the porous carbon electrode base material; drying the coating film by putting the porous carbon electrode base material with the coating film formed thereon under the condition of 50-200°C; and sintering the porous carbon electrode base material with the dried coating film formed thereon at 300-400°C to manufacture the porous carbon electrode with the coating layer formed thereon. A porous carbon electrode comprises a coating film prepared from a coating liquid including first carbon powder and second carbon powder which is 5-300 wt% to the weight of the first carbon powder.SELECTED DRAWING: Figure 1 |
