Coupling a PEM fuel cell and the hydrogen generation from aluminium waste cans. International Journal of hydrogen Energy, 2020。nchez, . Alvarez Gallegosa and . Sebastian, Recycling of aluminium to produce green energy, Solar Energy Materials amp。nez et al. [5] studied experimentally the generation of highpurity hydrogen gas from the chemical reaction of aluminium with sodium hydroxide. Their experimental results showed that the hydrogen yields are acceptable. They coupled a PEMFC with the hydrogen produced from chemical reaction [6]. This research concentrates on the use of PEMFCs in dwellings for the purpose of low power requirements. The building regulations in UK state that the dwelling emission rate (DER) should be calculated using a fixed assumption of 30% lowenergy lighting. Reasonable provision would be to provide, in the areas affected by the building work, fixed energyefficient light fittings that number not less than one per 25 m2 or one per four fixed lightings [7]. For these reasons, this research introduces and discusses one of the remaining challenges on the application test of PEMFC to real systems such as residential power generation. In addition, this paper describes two methods of producing lowpressure homemade hydrogen which can be coupled with a PEMFC to power energy saving lamps, particularly, lightemitting diode (LED) bulbs.

The platinum catalyst is also extremely sensitive to CO poisoning, making it necessary to employ an additional reactor to reduce CO in the fuel gas if the hydrogen is derived from an alcohol or hydrocarbon fuel. This also adds cost. Developers are currently exploring platinum/ruthenium catalysts that are more resistant to CO [1]. 附錄 25 Fig. 1. The proton exchange fuel cell. PEMFCs are used primarily for transportation applications and some stationary applications due to their fast startup time, low sensitivity to orientation, and favourable power to weight ratio. They have recently passed the test or demonstration phase and have partially reached the mercialization stage due to the impressive worldwide research effort. Fuel cells are different from batteries in that they consume reactant, which must be replenished, while batteries store electrical energy chemically in a closed system. Additionally, while the electrodes within a battery react and change as a battery is charged or discharged, a fuel cell39。 Dwelling 1. Introduction 2. Polymer electrolyte membrane fuel cells (PEMFCs)—also called proton exchange membrane fuel cells—deliver high power density and offer the advantages of low weight and volume, pared to other fuel cells. PEMFCs (Fig. 1) use a solid polymer as an electrolyte and porous carbon electrodes containing a platinum catalyst. They need only hydrogen and oxygen from the air to operate and do not require corrosive fluids like some fuel cells. They are typically fuelled with pure hydrogen supplied from storage tanks or onboard reformers. They operate at relatively low temperatures, around 80 176。 Fuel Cell。 參考文獻 19 參考文獻 [1] 康華光;《電子技術基礎》數(shù)字部分(第四版)北京,高等教育出版社出版, 2020 [2] 彭介華;《電子技術課程設計指導》北京,高等教育出版社, 2020 [3] 楊旭東,劉行景,楊興瑤;《實用電子電路精選》化學工業(yè)出版社, 2020 [4] 華成英;《電子技術》北京;中央廣播電視大 學出版社, 2020 [5] 童詩白;《模擬電子技術基礎》清華大學電子學教研組編,第三版,北京;高等教育出版社, 2020 [6] 康華光,陳大欽.電子技術基礎(模擬部分)(第四版) [M].北京:高等教育出版
