Fuel cell systems are devices that convert chemical energy into electrical energy. Among the mainstream high-temperature fuel cell systems on the market are SOFC (Solid Oxide Fuel Cells), SOEC (Solid Oxide Electrolysis Cells), and MCFC (Molten Carbonate Fuel Cells). High-temperature fuel cells offer numerous advantages, including the ability to utilize a variety of accessible fuels, high energy conversion efficiency, and the capability to recycle waste heat for heating, steam generation, or other industrial applications. As a result, they represent a clean and efficient energy conversion technology.

However, the commercialization of high-temperature fuel cells faces several challenges, including technical issues, manufacturing costs, and market acceptance. Thermal management is one of the key considerations in overcoming these obstacles. Fuel cell development teams must minimize heat loss to maintain system efficiency and ensure that components operate as intended. Incorporating insulation materials into the system design at an early stage is crucial to addressing these challenges. Factors such as performance, form, installation ability, stability, and cost are primary considerations for R&D teams when selecting insulation materials. Choosing the right insulation material can significantly streamline the design process.

Our microporous insulation materials have been applied in multiple world-renowned SOFC and SOEC projects. From initial design to mass production, we are fully involved in our customers’ project development processes.

In high-temperature fuel cell applications, operating temperatures typically range from 600°C to 1000°C. Our microporous insulation materials not only meet the high-temperature requirements but also offer insulation performance several times superior to traditional insulators at such high temperatures. The advantages of microporous insulation materials can address most of the challenges associated with insulation system design.
