A novel approach to pulsed laser deposition of platinum catalyst on carbon particles for use in polymer electrolyte membrane fuel cells
Beilstein J. Nanotechnol. 2023, 14, 190–204, doi:10.3762/bjnano.14.19
- graphitization were used as carbon supports. The best electrochemical measurement results were obtained for Pt deposited on Vulcan XC-72R. The peak power density measured for this material in a membrane electrode assembly (MEA) of a PEMFC (fed with H2/Air) was 0.41 W/cm2, which is a good result compared to 0.57
- catalysts in a membrane electrode assembly (MEA) of PEMFCs fed with H2/air. The materials with Pt deposited on Vulcan XC-72R (samples A and B), like commercial catalysts, formed a good quality catalyst layer on the Nafion membranes. However, we encountered some issues during electrode preparation from the
- the carbon supports coated with Pt as a catalyst in the fuel cell was investigated in a membrane electrode assembly (MEA) of PEMFCs fed with H2/air. The test samples coated with Pt by the PLD method were used as the cathode catalyst of the cell. The anode used was a layer of commercial Pt-based
Comprehensive characterization and understanding of micro-fuel cells operating at high methanol concentrations

- fuel concentrations. Using 20 M CH3OH causes a loss in performance in the passive µDMFC of 75% as compared to 4 M. It is thus clear that this system suffers from two problems: the Nafion® in the membrane electrode assembly (MEA), which is permeable to the fuel and the lack of tolerance of the cathode
- % open ratio were chosen for the anode and cathode, respectively. The silicon plates act as current collectors and gas diffusion layer (GDL) delivering the reactants to the catalyst layers that reach both sides of the membrane electrode assembly (MEA) by diffusion. A small piece of commercial MEA (E-TEK

- = 40%) were taken from a commercial membrane–electrode assembly (MEA) Celtec P1000 (BASF). In our experience, they have a rather reproducible performance. Therefore, we used them in order to ensure the most reliable comparison of different membranes in operating fuel cells. Membranes were prepared
Schottky junction/ohmic contact behavior of a nanoporous TiO2 thin film photoanode in contact with redox electrolyte solutions
Beilstein J. Nanotechnol. 2011, 2, 127–134, doi:10.3762/bjnano.2.15
- thin film of about 10 μm thickness with a roughness factor of about 1000. For Figure 2 and Figure 5–7, T/SP TiO2 was used and, in order to bring the other side of a Pt cathode in contact with air, a membrane electrode assembly (MEA) (1 cm × 1 cm) purchased from FC Development Co., Ltd., Japan was used
- measurements with membrane electrode assembly (MEA) attached to a Pt-mesh cathode. Cyclic voltammograms both in the dark (black line) and with light irradiation (gray line) at a nanoporous TiO2 photoanode (1cm x 1cm) in an aqueous solution of 10 wt % methanol (+ 0.1 M Na2SO4, pH 8.5) under an Ar atmosphere
