≧75mW/cm2@ 70~75℃, 0.44V                                     

6 MEA quality inspection 1. Visual inspection           
2. Performance test           
    3. Thickness measurement
*Note:Test condition of MEA3 and GDL
MEA3 (Nafion®115) and GDL
test condition
Single cell temperature 70℃
Concentration of MeOH 1M
MeOH flow rate 4X
Air flow rate 3X
 
 DMFC MEA Performance

Test condition
Single cell temperature 70~75℃
Anode 1M MeOH 4X
Cathode Air 3X
Gas diffusion layer Carbon paper
Test result MEA performance would be
sustained beyond 75mW/cm2@0.4V

Note: MEA performance will be varied by using different single cell and GDL.
