The concept of hydrogen fuel cells was invented in 1839 by Sir William Grove. BOC's director of sustainable energy, John Carolin, said:"The lessons from this and other projects will show that hydrogen fuel cell-powered vehicles could be a practical, attractive and a viable economic alternative to diesel- or petrol-fuelled vehicles."

BOC公司可再生能源部的主管约翰·卡罗林表示，&通过这辆汽车及其它同类项目所得到的经验将会告诉世人，将氢燃料电池做为汽车的动力来源这一想法是可以变为现实且颇具吸引力的，从经济角度来看，这种车也完全可以替代那些以汽油或柴油做动力的汽车&。

The borohydride is hydrogen source for an advanced fuel cell, Imol borohydride with water produces 4mol hydrogen and Imol of side product sodium metaborate. Regeneration of metaborate for recycle of boron brings forth a bright future to the new fuel cells. In this paper, a method for the preparation of sodium borohydride from sodium metaborate was proposed.

硼氢化钠是一种燃料电池的氢源，1mol硼氢化钠催化水解产生4mol的氢气及副产物偏硼酸钠，若能实现偏硼酸钠的循环利用，该燃料电池将有广泛的应用前景。

There are several references has been reported to reveal that adding phosphomolybdic acid hydrate PMo12 in the electrode of proton exchange membrane fuel cells and direct methanol fuel cell could promote performance.

目前已有相关研究发表将磷钼酸触媒(PMo12)应用於质子交换膜燃料电池以及直接甲醇燃料电池之电极触媒以提升电池效能。

A brief overview of current development in protonic ceramic membrane fuel cells with high temperature proton-conducting electrolytes is given, which points out that the poor chemical stability of traditional electrolyte materials for the protonic ceramic membrane fuel cell is the main obstacle for their applications.

本文介绍了以高温质子导体为电解质的质子陶瓷膜燃料电池的进展，指出传统质子陶瓷膜燃料电池较差的化学稳定性是阻碍其发展的重要因素。

Traditional fuel cells work by using a catalytic material to oxidise a fuel, such as hydrogen, and make an electric current flow between two electrodes.

传统的燃料电池是通过催化材料来氧化燃料，然后使两电级间产生电流。

Influenced by both obvious--Airstream trailers--and not-so-obvious sources--Stanley Kubrick's masterful film, 2001: A Space Odyssey --the Ford Airstream concept gets its power from a plug-in hydrogen fuel-cell hybrid setup. The system runs on electricity 100 percent of the time and, unlike most of today's fuel cells, is able to operate in the frigid temperatures of the frostiest winters.

由于受到预告片《气流》和Stanley Kubrick 2001年之作的著名影片《太空旅行》的影响，福特Airstream概念车动力来源于氢电混合动力装置，不像现在市场上大多数燃料电池，此装置可以让汽车完全依靠电力全时的行驶在路上，甚至在最寒冷的冬季也可以运行正常。

These features, along with high-precision processing technologies have helped to miniaturise these products. The micropump is 6.0mm in diameter and 24.0mm in length, the microvalve measures 3.5mm in diameter and 10.3mm in length. The products are small but ensure high functionality by incorporating fluid, structure and magnetic field analysis simulations. Development will contribute to enhanced miniaturisation, an indispensable prerequisite for portable device fuel cells. Through the optimal design of diaphragm operations, valve configuration to prevent fluid backflow, materials and layout, Alps has achieved the effective control of larger amounts of fluid in a smaller chassis for its micropump. The unit also employs low-voltage electromagnetic drive systems, which contribute to easy control and fuel cell system engineering.

The interfacial polarization resistances were unvaried during this period,suggested that the SDC modified anode was stable for the direct utilization of octane,and slight degeneration in the performance was associated mainly with the loss of OCV,which was possibly derived from a little carbon deposition within the SDC-coated anode where the level is so low that it almost has no effect to cause severe damage to the anode. The fuel composition and operation conditions had remarkably influence on the cell durability,implied that the stability of the fuel cells could be further improved by varying the iso-octane/O2 ratio and conducting a continuous operation.

燃料组分和测试条件对电池稳定性有着较大影响，说明通过改善O2/iso-octane比例以及维持电池在更长时间内放电能够获得更好的长期输出性能。
