Mixed proton—electron conducting

Proton-conducting materials [38-47], analogous to oxygen conductors but with stationary oxygen anions, can show mixed protonic-electronic conductivity, without considerable oxygen transport in hydrogen or water atmospheres [40,41], These materials have not been widely studied in comparison...

Defect-structure-wise there are two main routes to a mixed proton-electron conducting oxide. The simplest would be to dissolve protons compensated by electrons originating directly from hydrogen gas ... [Pg.8]

In general the charge carriers in mixed proton-electron conducting materials could be protons, oxygen ions (or oxygen vacancies), hydroxyl ions, electronic-holes and electrons. To determine the nature of the charge carriers and their transport numbers, various defect structure models have been presented [36-38]. These defect models were fitted to the total electrical conductivity data measured... [Pg.52]

The WGSR in a mixed protonic-electronic conducting SrCeo.9Euo.i03. membrane coated on a Ni-SrCeOa. support was studied by Li et al. [66], At 900°C a 46% increase in CO conversion was achieved, with the feed stream having a H2O/CO ratio of 2. [Pg.152]
