Challenges in Electrolyzer Performance Evaluation for Green Hydrogen Production

“…For water electrolyzers, addressing gas bubble formation is another critical aspect of a stack design. Gas production from a liquid can lead to issues such as reduced local current density, catalyst degradation, and gas crossover, because of the occupation of reaction sites by gas bubbles. , It is essential to carefully consider when borrowing stack designs from fuel cell systems, which typically convert gas to liquid. For instance, serpentine flow channels can dramatically interrupt the flow when gas bubbles are present .…”

Facile Deposition of a Spherical Ruthenium–Cobalt Alloy on Nickel Foam as a High-Performance Electrocatalyst for Alkaline Hydrogen Production

“…Despite these advantages, the current industrial method of hydrogen production heavily relies on fossil fuels, thereby exacerbating CO 2 emissions. , Consequently, significant efforts are underway to explore cleaner, more sustainable, and energy-efficient methods of hydrogen production . Nonfossil energy-based water electrolysis, which involves the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), is currently emerging as the most promising route for clean hydrogen generation. , The development of highly active and potent electrocatalysts to drive HER at faster rates is crucial for scalable hydrogen production. , Although water electrolysis can be conducted under both acidic and alkaline conditions, the former is considered technologically and commercially nonviable because of the lack of suitable counter electrode materials. − Consequently, efforts are directed toward developing highly active and stable HER catalysts for basic media to facilitate the commercialization of hydrogen production. , Although the HER in alkaline environments progresses slowly with a high overpotential, resulting in an energy-intensive process, the development of efficient and robust catalysts for this process is both crucial and challenging. , …”
