Microwaves and sorption on oxides: A surface temperature investigation

Article Abstract:

Microwave heating is not same as conventional heating, and it is believed that this difference, the microwave effect, may be interpreted to be due to selective local heating. The effective surface temperature increases with increasing the microwave power, approximately proportional to the square of the microwave power, for a particular adsorbent, adsorbate, and relative pressure used.

Electrooxidation of H2 and H2/Co mixtures on Pt/Ru-based gas-diffusion electrodes. (electrochemical impedance study of membrane-electrode assemblies in PEM fuel cells, part 2)

Article Abstract:

The behaviour of carbon supported Pt-Ru electrocatalysts has been investigated using the electrochemical impedance spectroscopy (EIS) method. Assessment of the potential dependence of EIS of carbon monoxide-poisoned anodes shows that three states can be seen on the electrode surface.

Usage, Impedance spectroscopy
