Microchanneled anode supports of solid oxide fuel cells

A novel anode with microchanneled structure has been prepared by a mesh-assisted phase-inversion process. The uniform microchannels templated by mesh apertures cross the anode, and act as efficient gas diffusion pathways, with one end open and the other end stopped with a less porous layer, which fu...

Description
Summary:A novel anode with microchanneled structure has been prepared by a mesh-assisted phase-inversion process. The uniform microchannels templated by mesh apertures cross the anode, and act as efficient gas diffusion pathways, with one end open and the other end stopped with a less porous layer, which functions as a support for thin electrolyte film and provides anode reaction sites. The solid oxide fuel cell supported on the microchanneled anode produced the maximum power densities of 550, 772 and 936mW/cm2 at 750, 800 and 850°C respectively, and no concentration polarization was found, suggesting there is efficient gas diffusion within the anode support. [Display omitted] •Microchanneled anodes were prepared by a mesh-assisted phase-inversion process.•Microchannels crossing anode supports provide efficient gas diffusion pathways.•The integrated structure is attractive as a porous support of SOFCs.
