Porous Silicon Membrane Based Formic Acid Fuel Cells for Micro Power Generation

издательство Книга по Требованию Химическая и лесная промышленность
Cтраниц 144        мягкая обложка       
Аннотация:With formic acid solution as the fuel, the micro fuel cells based on either p-type or n-type porous silicon membrane produce promising peak power density. The pore sizes can be controlled to range from microns to nanometers. It is shown that pore morphology determines the transport property of the porous silicon membrane through the volume fraction of the proton conducting phase in the membrane. A percolation model is shown to well explain the transport phenomena in porous silicon membranes. Fuel solutions with different formic acid concentrations are also tested. Micro fuel cells based on porous silicon membranes are developed and characterized in this work and are demonstrated to be a promising candidate for powering portable electronic instruments. Finally, micro fuel cells are fabricated using porous silicon membranes with different thickness and different pore morphologies, and their performances are tested. Proton conductivities of porous silicon membranes are derived using impedance spectroscopy. First, different pore morphologies of porous silicon are explored. The pore morphologies are characterized using scanning electron microscopy.

Использование альтернативных источников энергии

При серийном выпуске генератора в специфичных российских условиях себестоимость производства этого изделия оценивается порядка 15-25 $/кВт тепловой мощности. Расчетная рентабельность капиталовложений в освоение новации составляет более 60 % при сроке окупаемости менее 1,5 лет. Годовой экономический эффект применения генератора в среднем порядка 40-60 долл. на киловатт его тепловой мощности. Кроме того, промышленная продукция, включающая в себя ЭВГ, повышает экспортные возможности предприятий- производителей. Первоначальные затраты на изготовление действующего макета ЭВГ даже при накладных расходах предприятия 1200-1500 % не превышают 6000$. «Водородный» автомобиль Французский автомобильный концерн Re aul совместно с компанией uvera Fuel Cells планирует разработать серийный автомобиль, использующий в качестве топлива водород, уже к 2010 г. Схема расположения топливных элементов внутри автомобиля. uvera — небольшая американская компания, с 1991 года занимающаяся разработкой двигателей, альтернативных доминирующим сейчас бензиновым и дизельным.
