Current research status of fuel cell electrodes preparation devices was summarized.A roll press method was used,coating film thickness was ensured by controlling the amount of the solution of PET film and the speed of rotation of the roll,when it is 30℃,its power density can reach to 32.1mW/cm2[1].Method of roller to roller was used as shown in Fig.1,a theory of continuous coated controlling based on the statistical variance for electrode catalysts coating [2].
