Abstract

original image

For the next generation of fuel-cell applications The cover picture shows a scheme of hydrogen production from ambient temperature via oxidative reforming (OR) of n-butane over an Rh/CeO2 catalyst, which enables the development of a self-sufficient reforming system. In their Full Paper on p. 784 ff., K. Sato, K. Nagaoka et al. describe that a critical parameter of the catalyst for triggering the OR from ambient temperature is the number of easily reducible-surface CeO2 and exposed Rh sites. Increase in these values contribute to increasing catalyst bed temperature and lowering catalytic auto-ignition temperature, respectively, which results in decreasing the temperature for H2 reduction required prior to triggering the OR from ambient temperature.
