Abstract:

Electrolysis is seen as a promising route for the production of hydrogen from water, as part of a move to a wider “hydrogen economy”. The electro-oxidation of renewable feedstocks offers an alternative anode couple to the (high-overpotential) electrochemical oxygen evolution reaction for developing low-voltage electrolysers. Meanwhile, the exploration of new membrane materials is also important in order to try and reduce the capital costs of electrolysers. In this work, we synthesise and characterise a previously unreported anion-exchange membrane consisting of a fluorinated polymer backbone g

Abstract:

Water electrolysis is experiencing growing interest due to its importance in the transition to a carbon-neutral transportation sector and even in spaceflight it can play a vital role. Here, its typical application has been the oxygen generation for the life support of astronauts onboard a spacecraft or the International Space Station. However, in recent years the application of electrolysis for a new form of spacecraft propulsion is receiving increasing attention, as well. This technology is called Water Electrolysis Propulsion (WEP). So far highly toxic and expensive propellants have been use

Abstract:

Hydrogen is an efficient energy carrier with numerous applications in various areas as industry, energetics, and transport. Its potential depends also on the origin of the energy used to produce the hydrogen with respect to its environmental impact. Where the standard production of hydrogen from fossil fuels (methane steam reforming, etc.) doesn’t bring any benefit to decarbonisation of society. The most ecological approach involves water electrolysis using ‘green’ electricity, such as renewable power sources. Such hydrogen thus stores energy which can be used later.

Conventional proton-exchange membrane (PEM) water electrolysers use much thicker membranes (>175 µm) than their PEM fuel cell counterparts (<25 µm), which reduces hydrogen crossover but also reduces electrolyzer efficiency due to the increased Ohmic resistance1.

Due to the use of liquid water at the anode in conventional systems, the anode cannot be flushed with air or an inert gas to reduce the hydrogen concentration. If the liquid water supply i

This paper, in particular, centers on the design, trial production, and testing of carbon dioxide reduction electrolysis stacks. To optimize the stack performance, different plate materials were evaluated for their mechanical strength and corrosion resistance, resulting in the selection of aluminum alloy and 316L

Abstract:

The polymer electrolyte membrane and its contact with electrodes has a significant effect on the performance of fuel and electrolysis cells but the choice of commercially available membranes is limited. In this study, membranes for direct methanol fuel cells (DMFCs) were made by ultrasonic spray deposition from commercial Nafion solution; the effect of the drying temperature and presence of high boiling solvents on the membrane properties was then analyzed. When choosing suitable conditions, membranes with similar conductivity, water uptake, and higher crystallinity than comparable commercial

The merging of conventional Alkaline Electrolysis (AEL) and Proton Exchange Membrane Water Electrolysis (PEMWE) has led to the development of Anion Exchange Membrane Water Electrolysis (AEMWE). At this juncture, both AEL and AEMWE technologies offer an advantage over PEMWE as they do not require critical raw components and materials (CRM).[1] While AEMWE has demonstrated higher efficiencies than AEL with thin membranes and low concentrations of KOH, AEL technology addresses the significant stability challenge posed by anionic membranes by employing KOH electrolyte with novel zero-gap configura

Abstract:

Hydrogen production through water electrolysis has attracted renewed interest in converting low-carbon electricity into hydrogen in the last few years. The so-produced hydrogen can be used as a reagent for the chemical industry, as a fuel, or for long-term storage of excess renewable energies, contributing to reducing CO2 emissions in many sectors. The most mature and commercially available technology developed for hydrogen production is alkaline water electrolysis (AWE), where nickel-based electrodes are exploited as an anode and cathode and are immersed in concentrated KOH electrolyte (5-6 M

Abstract:

By 2030 up to 50% of energy is expected to be carried in the bonds of H2. Global electrolysis capacity must increase from the current 240 MW to an anticipated 300 GW in 2030 and 3500 GW in 2050 to enable this transition. Alkaline and PEM electrolyzers are commercially mature with the currently market share of new installations roughly an equal split between these technologies. However, each of these electrolyzers are associated with challenges – alkaline electrolyzers operate at low current density, and require high concentration electrolytes (30 wt% KOH) to conduct hydroxides through the poro

Abstract:

Alkaline water electrolysis is one of the important methods for generating high purity hydrogen. Alkaline electrolysis, because of the possibility of using relatively inexpensive electrode materials, is more economical than hydrolysis in acidic medium; the medium is also less corrosive. The challenges in water electrolysis in general are to reduce the cost, energy consumption and maintenance, hence increase the efficiency of the overall process. An important consideration in the above is the separator between the two electrode compartments, which has to be such that it minimizes (or eliminates

Anion exchange polymer electrolytes enable the use earth-abundant catalysts, non-fluorinated solid polymer electrolytes, and low-cost cell components for sustainable, low-temperature water electrolysis to produce green hydrogen. However, long-term durability of the anion exchange membrane water electrolysis (AEMWE) needs to be demonstrated at high current density (i.e., > 1 A/cm2).
