Checking graphite and stainless anodes with an experimental model of marine microbial fuel cell [PDF]

, 2008
A procedure was proposed to mimic marine microbial fuel cell (MFC) in liquid phase. A graphite anode and a stainless steel cathode which have been proven, separately, to be efficient in MFC were investigated.

Space–charge theory applied to the grain boundary impedance of proton conducting BaZr0.9Y0.1O3−δ. [PDF]

, 2010
The specific grain interior and grain boundary conductivities, obtained from impedance spectroscopy and the brick layer model, are reported for BaZr0.9Y0.1O3−δ as a function of pO2 and temperature. pO2-dependencies were indicative of dominating ionic and
