As coal, oil, natural gas and other fossil energies are increasingly exhausted, the greenhouse effect and environmental pollution are becoming more and more significant. Hydrogen energy, with merits of zero carbon emission, has become an important direction of the current world energy revolution. Hydrogen energy equipment is the key to realizing safe storage and efficient utilization of hydrogen energy, including hydrogen storage bottles, high-pressure hydrogen storage pressure vessels, hydrogen transport pipes, valves, instruments, etc. At the same time, the performance of the hydrogen energy equipment is continuously influenced by the extreme environmental effects. Under the conditions of high pressure and high temperature or extremely low temperature, hydrogen energy equipment materials are often faced with damage risks such as hydrogen embrittlement and hydrogen penetration. The dissociation of hydrogen into small atoms under the environmental conditions makes hydrogen penetration unavoidable, which increases the susceptibility of cracking and fracture of the material. Therefore, it is of paramount importance to study the damage and mechanical behavior of hydrogen energy equipment materials in hydrogen environment for the safety and reliability of the system. On the other hand, fuel cell is a device that directly converts the chemical energy of fuel into electric energy, with high conversion efficiency, and it is the best utilization technology of hydrogen energy. Fuel cell consists of electrode, electrolyte, bipolar plate, sealing layer and other components. In the long-term hydrogen environment, fuel cell materials are prone to hydrogen damage and even cracking, which affects the structural integrity of fuel cell, resulting in a decrease in performance and service life of fuel cell. Especially for solid oxide fuel cell, its operating temperature is up to 600~800℃, and the material is prone to occur creep failure in hydrogen environment. It is of great significance to study the hydrogen damage behavior and adopt reliable methods to suppress hydrogen damage of fuel cell material for long-term reliable operation.
Therefore, the theme of this Research Topic is the mechanical strength and damage behavior of the materials used for hydrogen equipment and fuel cells during long-term service in hydrogen environment. The goal is to share and disseminate the latest research progress on hydrogen equipment materials, to better understand the influence of extreme hydrogen environment (high temperature, high pressure, low temperature, hydrogen environment) on the service performance of the materials used for hydrogen equipment materials and fuel cells, and to enhance the safety and reliability of the applications.
The scope of this Research Topic focuses on recent advances in the field of the damage and mechanical behavior of hydrogen equipment and fuel cell materials. The topics of interest include but are not limited to the following:
• Developments of advanced hydrogen equipment materials
