    Notes: Abstract Better performance of and higher electrocatalyst utilization in proton-exchange membrane fuel cells equipped with thin film electrodes is achieved by exploiting pore forming additives in the electrode recipe formulation. Preparing the membrane–electrode assembly by a hot spraying procedure already provides 35% porosity. Additional coarse porosity is obtained by adding pore formers to the electrocatalyst slurry which is used for the hot spraying process. This allows for a better access of oxygen from air to the depth of the cathode. For air operation at ambient pressure and low catalyst loading of 0.15mgPtcm-2 a current density of 200mAcm-2 at 0.7V cell voltage can be obtained with such electrodes.

    Hydrogen fired PAFCs: an experimental investigation into the optimal utilization of impure, recycled hydrogen (2000)
    Springer
    Journal of applied electrochemistry 30 (2000), S. 323-331 
    Details
    ISSN: 1572-8838
    Keywords: fuel cell ; hydrogen recycle loop ; operation parameters ; PAFC operation

    Topics: Chemistry and Pharmacology , Electrical Engineering, Measurement and Control Technology
    Notes: Abstract Phosphoric acid fuel cells (PAFCs) had been developed for cogeneration plants based on natural gas as fuel. Operation of phosphoric acid fuel cells on hydrogen requires recycling of unspent hydrogen from the anode exhaust for obtaining highest efficiency. But recycling rates are limited due to accumulation of inert gases. Theoretical calculations and experimental data on optimizing this operation mode with respect to highest electrical energy efficiency are compared. The results are verified in a 100 cm2 PAFC unit. From the data obtained with a Fuji 2 kW PAFC, the performance of large units with hydrogen recycling is predicted.

    Notes: Abstract We have combined the techniques of frequency-modulation spectroscopy (FMS) and photochemical-modulation spectroscopy to carry out high-resolution, high-sensitivity absorption measurements on the formyl and amino radicals. Using the (0,90, 0)-(0,01, 0) band of theÃ,2 A″- $$\tilde X$$ ,2 A′ transition of HCO at 614 nm, we obtained a sensitivity limit for absorption of 1.5×10−6. Reconstructed spectra of several HCO lines are presented.
