This study aims to examine the influences of substrates/diffusion layers (DL) and oxygen reduction reaction catalysts (M , revealed that the roughness factor of the DL mainly determined the electrode performance for both water electrolyzer (WE) and fuel cell (FC) operations, while the contributions of porosity and substrate material were insignificant. When Pt-Ru was utilized as the M O R R instead of Pt, WE performance was enhanced and the electrode performance was assessed by analyzing round-trip efficiencies (ε . Improved efficiency was related to the additional catalytic action by Ru toward ORR during WE operation.

“…Though Pt is the most commonly preferred M ORR , it is very expensive and its usage is as high as 50-80% of total loading [7][8][9][10][11][12][13][14]. Hence, it is important to find alternative M ORR s that are less costly and provide acceptable performance.…”

“…The number of publications per year in this cluster has recently increased. Regenerative fuel cells (RFC) are the topic of cluster II-C, which can be utilized as both water electrolyzers and fuel cells [43][44][45]. RFC can reduce the total components and weights of the power generator/accumulator, which is beneficial for some applications, such as use in a space shuttle.…”

Abstract:Water electrolysis for hydrogen production has received increasing attention, especially for accumulating renewable energy. Here, we comprehensively reviewed all water electrolysis research areas through computational analysis, using a citation network to objectively detect emerging technologies and provide interdisciplinary data for forecasting trends. The results show that all research areas increase their publication counts per year, and the following two areas are particularly increasing in terms of number of publications: "microbial electrolysis" and "catalysts in an alkaline water electrolyzer (AWE) and in a polymer electrolyte membrane water electrolyzer (PEME).". Other research areas, such as AWE and PEME systems, solid oxide electrolysis, and the whole renewable energy system, have recently received several review papers, although papers that focus on specific technologies and are cited frequently have not been published within the citation network. This indicates that these areas receive attention, but there are no novel technologies that are the center of the citation network. Emerging technologies detected within these research areas are presented in this review. Furthermore, a comparison with fuel cell research is conducted because water electrolysis is the reverse reaction to fuel cells, and similar technologies are employed in both areas. Technologies that are not transferred between fuel cells and water electrolysis are introduced, and future water electrolysis trends are discussed.

The design of electrodes for URFC (unitised regenerative polymer electrolyte fuel cells) requires a delicate balancing of transport media. Gas transport, electrons and protons must be carefully optimised to provide efficient transport to and from the electrochemical reaction sites. This review is a survey of recent literature with the objective to identify common components and design and assembly methods for URFC electrodes, focusing primarily on the development of a better performing bifunctional electrocatalyst for the oxygen reduction and water oxidation. Advances in unitised regenerative fuel cells study have yielded better performing oxygen electrocatalysts capable of improving energy efficiency with longer endurance and less performance degradation over time. Fuel cells using these electrocatalyst have a possible future as a source of energy.
