Abstract
The Department of Energy (DOE) has identified the reduction of H2 production costs as a prominent objective. Therefore, any factor that influences the system's functionality and subsequently production cost is deemed significant. The stability of the cathode is a crucial factor in ensuring high operational reliability; however, its treatment in the existing literature remains inadequate. This review aims to identify the key challenges associated with the stability of HER electrodes and provides a comprehensive understanding of various cathodic degradation mechanisms. In the present investigation, genuine circumstances encountered by cathodes in the industrial sector are considered. Special attention is devoted to Fe-based materials, which are deemed favorable and economical options, whereas the deterioration mechanism of Ni-based counterparts, such as cutting-edge materials, is scrutinized. Furthermore, the limitations of using the E-pH diagram, which is a commonly employed tool for predicting stable phases under specific conditions, are discussed. In addition, the cost implications of developing alkaline water electrolyzer (AWEL) stacks are considered. Finally, a comprehensive discussion is presented on the durability of cathode plates, including an analysis of the factors that impact their predicted lifetime and protocols that facilitate the acquisition of more realistic stability results.
期刊介绍:
Progress in Materials Science is a journal that publishes authoritative and critical reviews of recent advances in the science of materials. The focus of the journal is on the fundamental aspects of materials science, particularly those concerning microstructure and nanostructure and their relationship to properties. Emphasis is also placed on the thermodynamics, kinetics, mechanisms, and modeling of processes within materials, as well as the understanding of material properties in engineering and other applications.
The journal welcomes reviews from authors who are active leaders in the field of materials science and have a strong scientific track record. Materials of interest include metallic, ceramic, polymeric, biological, medical, and composite materials in all forms.
Manuscripts submitted to Progress in Materials Science are generally longer than those found in other research journals. While the focus is on invited reviews, interested authors may submit a proposal for consideration. Non-invited manuscripts are required to be preceded by the submission of a proposal. Authors publishing in Progress in Materials Science have the option to publish their research via subscription or open access. Open access publication requires the author or research funder to meet a publication fee (APC).
Abstracting and indexing services for Progress in Materials Science include Current Contents, Science Citation Index Expanded, Materials Science Citation Index, Chemical Abstracts, Engineering Index, INSPEC, and Scopus.
