Design of next-generation ceramic fuel cells and real-time characterization with synchrotron X-ray diffraction computed tomography.

ABSTRACT: Ceramic fuel cells offer a clean and efficient means of producing electricity through a variety of fuels. However, miniaturization of cell dimensions for portable device application remains a challenge, as volumetric power densities generated by readily-available planar/tubular ceramic cells are limited. Here, we demonstrate a concept of 'micro-monolithic' ceramic cell design. The mechanical robustness and structural integrity of this design is thoroughly investigated with real-time, synchrotron X-ray diffraction computed tomography, suggesting excellent thermal cycling stability. The successful miniaturization results in an exceptional power density of 1.27 W cm^-2 at 800 °C, which is among the highest reported. This holistic design incorporates both mechanical integrity and ele
