In order to prevent global warming and keep energy conservation, we need a compact and high efficient power source. A Stirling engine, which has excellent characteristics such as high ideal efficiency and low pollution, is one of the suitable power sources for a comfortable life in the future. In this study, we aim to develop a high efficient Stirling engine. And a ceramics heat exchanger is developed. It has high heatproof performance and high heat conduction, then the Stirling engine can have higher operating temperature. We discuss about performance of the ceramics heat exchanger based on the test results of a prototype Stilring engine.
