Abstract
Solid oxide fuel cells (SOFCs) are recognized as highly efficient energy-conversion and eco-friendliness technologies. However, the high-temperature operation of conventional SOFCs at 800–1000 °C has hindered their practical applications due to the accelerated materials degradation and the resulting performance failures. Therefore, developing lower-temperature SOFCs (LT-SOFCs) seems necessary. With respect to LT-SOFCs, developing highly active cathode materials with long-term stability has been identified to be the priority, where cathode surface engineering has surfaced as a pivotal technique to bolster cathode functionality. This review delves into the myriads of surface modification strategies, including solution infiltration, atomic layer deposition (ALD), one-pot method, exsolution, pulsed laser deposition (PLD), and electrospinning (ES). Each method is scrutinized for its potential to enhance the cathode oxygen reduction reaction (ORR), a critical process in LT-SOFCs, while also fortifying the structural stability of cathode materials. This paper also meticulously evaluates recent breakthroughs in cathode surface engineering with highlighting the nuanced interplay between microstructural features and electrochemical performance. The technical challenges that persist in the practical application of LT-SOFCs are analyzed in this work and the possible further research directions are also suggested for overcoming the challenges towards significantly improved cathode performance including activity and stability.
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.
