• Their novel carbon–air battery has its fuel container—catalytically activated carbon—integrated by anode support. Its most prominent feature, however, is the addition of a ceramic membrane that has been specially designed to allow efficient CO2 separation and thus increase fuel utilization efficiency.
  • This novel membrane not only proved to be perfectly gas-tight, but also provided a temperature-dependent excellent CO2 permeation flux much higher than the values reported for similar membranes.
  • "Such an improvement is likely due to the much improved densification of the membrane fabricated by using the technique reported here", the researchers point out. Moreover, at the operating temperatures for SOFC applications, which are as high as 850°C, attractive power densities and open-circuit voltages can be obtained. Applications may include portable energy supplies that have to be run at high temperatures.
