Carbonization and decarbonization of alkaline matrix fuel cells

The paper deals with some questions concerning carbonization and decarbonization of alkaline electrolyte in matrix fuel cell (FC). It is shown that there is an equilibrium ultimate level of carbonization that depends on CO2 content in gases delivered into FC and FC electric loading. Electrolyte decarbonization takes place at the increase of FC load current with CO2 emission at hydrogen electrode end. The possible mechanisms of electrolyte carbonization and decarbonization are suggested.

Pyrolized polyacrylonitrile as a feasible electrode material for electrochemical power sources

In the current paper electrospun nanofiber mats were derived from polyacrylonitrile (PAN). The temperature influence on the volumetric and surface composition of the resulting pyropolymers was studied by means of elemental analysis and X-ray photoelectron spectroscopy.
