Paperzilla title
Green Hydrogen Dream: Can AEM Electrolyzers Deliver?

The review explores different water electrolysis technologies for green hydrogen production, emphasizing the potential of anion exchange membrane (AEM) electrolyzers due to their cost-effectiveness and use of non-noble metal catalysts. While AEM electrolyzers show promise, challenges related to membrane stability and system-level integration need to be addressed for large-scale commercialization.

Explain Like I'm Five

Scientists found a way to make clean fuel from water using a special machine. They are trying to use cheaper parts for it, but still need to make sure the machine is strong and easy to use for everyone.

Possible Conflicts of Interest

The authors acknowledge funding from organizations involved in hydrogen energy research, which could potentially introduce bias.

Identified Limitations

Limited comparison with other technologies
The paper lacks a detailed comparison of AEM electrolyzers with other technologies, making it difficult to assess its true potential.
Lack of system-level analysis
The paper primarily focuses on material development, but does not adequately address system-level integration or cost analysis, which are crucial for commercialization.
Insufficient discussion of scaling challenges
The review does not delve deep into the technical challenges related to scaling up AEM electrolyzers, such as stack design and manufacturing.

Rating Explanation

The paper provides a comprehensive overview of water electrolysis technologies, focusing on the promising potential of AEM electrolyzers. The discussion of recent advancements in electrode materials and challenges is valuable. However, the limited comparison with other technologies and the lack of system-level analysis prevent a higher rating.
