Fuel cell electrodes prepared by e-beam evaporation of Pt compared with commercial cathodes: Electrochemical and DMFC behaviour

An increment in the electroactive surface area and a fuel cell performance comparable to those obtained using commercial electrodes is found. Besides, the power obtained per unit mass of catalytic material also increases. Therefore, it can be concluded that electron beam evaporation of Platinum on carbon support shows to be a suitable procedure to obtain efficient fuel cell electrodes.
