Resumo
In this work, results of the preparation of Membrane
Electrode Assemblies (MEA) catalyst layer are shown to be
faster and highly reproducible by using the sieve printing
technique. The results were compared with those obtained by
spray and hot pressing methods. The experiments were carried
out in a 25 cm2 single fuel cell. SEM was used to investigate
the electrodes morphology. The MEAs performance was
measured by polarization curves. It was observed that the sieve
printing method is significantly more accurate and faster than
spray one. Such features allow manufacturing larger active
areas, for stack fabrication. In addition, this deposition
technique produces MEAs with 39,8 % higher power density in
the operating voltage region.
