Comparative Study on Composite Electrodes for Medium Temperature PEFCs

1 Results The phenomena that affect the membranes could be found in the electrodes when they operate at medium temperature,due to the utilisation of Nafion as an ionomer in the catalytic layer.An approach to improve the mechanical properties of the ionomer in the catalytic layer was used: different inorganic compounds (zeolite,titania and zirconia),having different chemical-physical properties,were selected as inorganic fillers due to their water retention capacity and to act as mechanical reinforce by ...
