An ingenious spin on fuel cells The cover picture shows a genie watching an organometallic fuel cell to observe its reaction mechanism. In their Full Paper on p. 1368 ff., T. Hibino, S. Ogo et al. describe an organometallic [NiIIRuIV] peroxo catalyst that functions as the cathode in a fuel cell with a 240 % increase in power output over their previous systems. The organometallic catalyst is active in both solid and solution phases and allows for observation of the mechanism, providing opportunity for further improvement to the hydrogen economy.
