플라스틱을 기판으로 이용한 소형 고분자전해질 연료전지

The fabrication and performance evaluation of new miniature PEMFC based on plastic(polyimide) substrate are presented in this paper. Polyimide substrate provide a current collector and flow channel. The electronic conduction on the nonconductive polymer was enabled by sputtering of gold on the top of the polyimide. Strong adhesion and high con- duction in binding of elements are obtained by using the method which attached adhesive and conductive component sep- arately between elements instead of using mixture of these components. Hydrogen is provided by the hydrolysis of sodium borohydride (NaBH4). Operating on air at 22 o C and atmospheric pressure, the measured peak power density was 20.7 mW/cm 2
