“…In electrolysis at 120~ NiCoO., anodes prepared by thermal decomposition showed oxygen evolution potentials similar to those of NiCo204 and La0.sSr0.~CoO:~ anodes at a current density of 1000 mA/cm 2 (42,43). At lower current densities (100-200 mA/cm2), NiCoO2 was superior to the other anode materials.…”

“…For example, in 30% KOH electrolyte at I45~ La0..~Sr0..~CoO:~ was about 120 mV superior to NiCo204 at 1000 mA/cm 2 (38). However, under similar conditions (120~ 1000 mA/cm~), cells with La0..~Sr0.sCoO:~ anodes showed 0.1V higher voltages than similar cells with NiCo~O4 anodes (42). A mixed La-Sr-Co oxide of unspecified composition, deposited on a Raney nickel substrate, was 180 mV more efficient than an unactivated nickel mesh anode at a current density of 1000 mA/cm 2 in 40% KOH electrolyte at 160~ (23).…”

In recent years, considerable progress has been made in developing alkaline water electrolysis anodes. Several laboratories have reported oxygen evolution overpotential reductions of 100-150 mV or more, relative to uncatalyzed nickel. Some candidate anode materials have shown stable operation for thousands of hours under typical commercial electrolysis conditions. Preferred e]ectrocatalysts have been the mixed metal oxides, especially the AB204 spinels and ABO:~ perovskites. Other metal oxides, alloys, and high surface-area forms of nickel have also been studied. This review summarizes recent work in developing practical alkaline water electrolysis anodes.

“…Between organic materials, polysulfone and polyphenylene sulphide were promising technologies, reaching stability temperature up to 120°C to 200°C, with needed improvements in surface properties, to solve their poor wettability. Vandenborre et al showed NiCo 2 O 4 and NiCo 2 S 4 as the best anode and cathode electrocatalysts 205 …”

“…Vandenborre et al showed NiCo 2 O 4 and NiCo 2 S 4 as the best anode and cathode electrocatalysts. 205 In 1983, Noranda Research Centre 206 shows that Teflon with potassium titanate has the lowest resistance factor as separator, although the fragility and hydrophobicity must be solved. Additionally, stability and good electrocatalytic performance are shown with nickel electrodes, plasma-sprayed with nickel/aluminium or nickel/stainless steel powders, and the most promising anode type tested to date was plasma-sprayed Ni/SS alloy.…”

Summary Water‐based hydrogen production is currently an attractive research field, as it provides a greener method to produce hydrogen than existing alternatives. Green hydrogen is expected to progressively replace fossil fuels, which are highly harmful environmentally. This paper presents a critical analysis over time of the main water splitting technologies currently in use for sustainable hydrogen production. As a result of the critical analysis, all the studied techniques have been ordered chronologically in the way that it is possible to understand how new materials have driven to new techniques, more efficient and less expensive. This allows having a complete vision of these technologies. A high level of maturity has been reached in electrolysis, while other techniques still have a long way to go, although many improvements and relevant advancements have been made over the years. The paper offers a global and comparative vision of each technology. From this, it is possible to identify the different paths where efforts are needed to make water‐based hydrogen production a mature, stable and efficient technology.

“…In this case, the usage of perfluorocarbon cation-exchange membranes and inorganic ion exchange membranes [173] is being made. Especially, it is reported that solid polymer electrolyte (SPE) method produces hydrogen gas at high efficiency, where perfluorocarbon cation-exchange membranes are used with catalyst coated as electrodes [174].…”

Membrane science is a relatively new area of applied chemistry and chemical engineering and plays a vital role in the field of alternative energy and separation applications. The field of membrane science is therefore an emerging area with enormous industrial and public health significance. Today, various kinds of separation membranes have been studied and utilized industrially in different processes including reverse osmosis, nanofiltration, ultrafiltration, microfiltration, electrodialysis, and pervaporation. Technical feasibility of all these processes largely depends on membrane and its properties. Among the separation membranes, ion exchange membranes are one of the advanced separation membranes. Therefore, this chapter addresses on different types of ion exchange membranes with reference to their preparation, properties, as well as their industrial applications. Although ion exchange membranes are broadly classified into homogeneous and heterogeneous membranes, this chapter also covers other types of ion exchange membranes such as amphoteric, mosaic, bipolar, interpolymer, and graft and block copolymer membranes. At the end, prospectives and conclusions on the ion exchange membranes have also been highlighted. The relevant literature was collected from different sources including Google sites, books, reviews, and research articles.
