1. Introduction. Nickel is a hard, ductile, silvery-white transition metal; it is the 28th element in the periodic table. It may exist in several oxidative states (from −1 to +4); nevertheless, the +2 oxidation state (Ni 2+) is the most widespread in the environment and biological systems [].Nickel belongs to the ferromagnetic elements, and it is naturally …
Valuable, "green" H 2 can be produced with a microbial electrolysis cell (MEC). To achieve a high volumetric production rate of high purity H 2, a continuous flow MEC with an anion exchange membrane, a flow through bioanode and a flow through Ni foam cathode was constructed.At an electrical energy input of 2.6 kWh m −3 H 2 (applied …
