Then the catalyst ink was sprayed onto the Teflon-treated carbon paper to prepare the resulting electrode
with an active area of 2.5 2.5 cm2 and a catalyst loading of 1 mg cm2.
The AEM sandwiched between the anode and cathode electrodes was hotpressed at 0.5 MPa for 5 min at 60 C to obtain MEA for fuel cell test.
