There are significant barriers to the introduction of hydrogen fuel cells for transportation, including the high cost of fuel cell systems, the current lack of a hydrogen infrastructure, and the relatively low fuel efficiency when using hydrogen produced from hydrocarbons. Here, we show a new solid oxide fuel cell that combines a catalyst layer with a conventional anode, allowing internal reforming of iso-octane without coking and yielding stable power densities of 0.3 to 0.6 watts per square centimeter. This approach is potentially the basis of a simple low-cost system that can provide significantly higher fuel efficiency by using excess fuel cell heat for the endothermic reforming reaction.
