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.

Durability Test

Test condition

Single cell temperature 40℃

Density of
electric current 81mA/cm²

Anode 10vol% MeOH

Cathode 500C.C./min Air

Gas diffusion layer Carbon paper

Test result Performance of MEA could be
sustainable in the test with high MeOH conc. operating

Product Applications

Applied to Fuel Cell in terms of methanol as anode fuel directly.
