Abstract: A diesel fuel additive includes a cetane number improver and an at least one organometallic combustion catalyst in solution and/or at least one metal-oxide combustion catalyst in suspension.

Abstract: A method for making a bi-metallic electrocatalyst produces a non-platinum group metal (non-PGM), bimetallic oxide crystalline catalyst showing low overpotential in both oxygen evolution reactions (OER) and oxygen reduction reactions (ORR) in a metal-air battery and/or fuel cell applications. The bimetallic oxide is formed to be in electrical communication with a catalyst support particle, and with the catalyst support particle, in turn, in electrical communication with an air-permeable electrode. A metal-air storage cell, optionally configured as part of a battery, includes a bi-metallic electrocatalyst. An electrical management system includes a metal-air storage cell.
