科技博物館應用燃料電池小火車在教育內涵之探討

A Study of Fuel Cells Applied in the Small Train within the Education Activity at the Science Museum

能源工程和環境保護是本世紀關係人類生存及發展的重要議題，由於燃料電池也是具有潛力的綠色發電工具，目前廣受各國重視，預料可成為本世紀重要的能源裝置。燃料電池（fuel cell）是將化學能直接轉換成電能，可以說是一種綠色環保發電機，將是推廣潔淨能源及動力科技之未來的趨勢，而近期燃料電池的發展是以氫氣為燃料之低溫型的質子交換膜燃料電池（PEMFC）為主，因此國立科學工藝博物館（以下簡稱：工博館）結合火車的趣味性及未來能源科技的新奇性，把質子交換膜燃料電池應用在乘坐式小火車上，以推廣燃料電池新知及永續環境的教育。本文藉由工博館之燃料電池小火車（以下簡稱：小火車）之設備及營運過程的觀察，來探究小火車之科教意義，並提供未來辦理燃料電池科教活動及開發相關教具、教案時之參考，以達到珍惜能源、愛護環境之教學。

The energy engineering and the environment protection are the important issues for the development of human survival in this century. Fuel cell battery is also a potential tool in green electricity generation which is valued by many countries. It is expected to be an important energy device in this century. The function of fuel cell is to transfer the chemical energy into electricity. It can be taken as one kind of generators for green environmental protection which will become trends for the clean energy and power technology in the future. Therefore, this study tries to introduce the small train, which used the low temperature of Proton Exchange Membrane Fuel Cells as its power to promote the new knowledge of fuel cells and the education of ecological environment. This paper also tried to discuss the context of education activity of the small train through the observation of the small train working process at the National Science & Technology Museum and hoped to provide suggestions for the fuel cells technology education activity in the future. It will be helpful for designing and developing related instructions and teaching aids for such, hence to achieve the teaching goal of treasuring energy and our environment.
