Dalian Chemical Industry Co., Ltd. managed solid oxide fuel cell stack has a power generation of 3,000
Recently, the Medium-High Temperature Solid Oxide Fuel Cell Research Group (DNL0302 Group) at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, successfully conducted a power generation test on a tubular solid oxide fuel cell stack. The system achieved a power output of 3 kilowatts, marking a significant step forward in their research efforts.
The tubular cell stack comprises 60 anode-supported tubes, each measuring 100 cm in length with an outer diameter of 23 mm, arranged in parallel. Each individual cell demonstrated an average open-circuit voltage exceeding 1.0 volts and produced over 50 watts of power. This successful test confirmed the high level of consistency among the cells, uniform distribution of fuel gas and air within the stack, and efficient current collection and extraction. These achievements lay a solid foundation for future development of high-power solid oxide fuel cell stacks.
Solid oxide fuel cells are versatile energy conversion devices capable of utilizing various fuels such as natural gas, coal gasification purified gas, and biomass gas. They offer a remarkable electrical efficiency of up to 65% or higher, and when used in combined heat and power (CHP) systems, the overall energy utilization can exceed 90% without emitting any pollutants. Their potential applications span both distributed and centralized power generation, making them a promising technology for the future of clean energy production.
The Dalian Institute of Chemical Physics is actively advancing tubular solid oxide fuel cell technology, which is currently supported by the "863" National High-Tech Research and Development Program under the Ministry of Science and Technology. This ongoing research aims to improve performance, reliability, and scalability for broader commercial deployment.
