| Abstract: | The principle, the characteristics and the application in fabrication of membrane electrode for fuel cells were discussed with the testing results of different spraying methods. The cell membrane electrode was made with spray of high-pressure airless spraying, compressed air spraying, mixed air spraying, electrostatic spraying and ultrasonic enhanced spraying. The high-pressure airless spraying and mixed air spraying were chosen through the discussion of the several spraying methods. Experiments show that the mixed air spray can reach the needs of design in the respect of functions of the sprayed coating, economics and deposition rate. |
