This week’s digest features four interesting papers on solid oxide cells. I would like to thank all reviewers for their diligent and continuing service to The Electrochemical Society, which made the following publications possible.
The paper by Zhu et al. presents a novel concept to generate pure compressed hydrogen through a combination of two electrochemical cells based on oxygen-ion conducting ceramics and proton-conducting ceramics. Through a theoretical analysis, the authors show that it is possible to utilize one single device to produce pure and compressed hydrogen from hydrocarbons and steam without an external electricity supply.

Hussain et al. report the performance of an SOFC powered by CH4/H2 gas mixtures with a ceramic anode infiltrated with an electrocatalyst having various Ni-to-GDC ratios. Enhanced fuel oxidation kinetics and ceramic anode stability were observed at 600oC with a proper Ni/GDC ratio. (Contact author: Eric Wachsman at ewach@umd.edu)
The article by Anke Hagen and her colleagues describes the direct use of methane as the fuel for metal-supported SOFCs to investigate the internal reforming behavior of anodes infiltrated with Ni/GDC particles. They also found that the Ni content in the metal support is critical for the complete methane conversion. (Contact author: Anke Hagen at anke@dtu.dk)
Riedl et al. report a method to study the oxygen reduction kinetics of LSF on single crystal YSZ by decorating LSF with platinum nanoparticles. The negative pO2 dependence of ASR indicates the strong catalytic effect of platinum. (Contact author: Christoph Riedl at christoph.riedl@tuwien.ac.at and Juergen Fleig at juergen.fleig@tuwien.ac.at)
