Abstract

The electrochemical performance of solid oxide fuel cells (SOFCs) operating directly with pure dimethyl ether (DME), DME + air, and DME + N 2 was studied for temperatures ranging from 550 to 650°C. The power densities achieved for DME + air operation at 550°C were approximately 70 and 112% greater than those for pure DME and DME + N 2, respectively. Kinetic modeling and mass spectrometry data indicated adding oxygen (via air) to DME promoted decomposition into primarily H2, CO, and CH4. The increased performance achieved for SOFCs utilizing the DME + air fuel mixture was attributed to oxygen promoted decomposition of DME.
