原创 RIM燃料电池专利可望突破移动设备续航能力瓶颈

虽然RIM最近少有新的产品推出，但是远在滑铁卢的RIM工程师们并没有停下手中的工作。最近在美国专利局又通过了一项RIM申请的专利，内容就是燃料电池。该技术试图将燃料电池引入移动设备，来帮助设备在续航方面有所改善和突破。

电池放置的位置位于键盘与主板之间。专利说明原文如下：

A mobile device having: a keyboard; a printed circuit board having at least one contact responsive to the keyboard; and a fuel cell assembly having: a fuel cell located between the keyboard and the printed circuit board, the fuel cell having a membrane and at least one aperture corresponding with the at least one contact; a tank adapted to store a fuel for the fuel cell; and piping connecting the tank with the fuel cell, where the fuel cell ventilates through the keyboard. Alternatively, the fuel cell acts as the printed circuit board and at least one contact for the keyboard is printed onto the fuel cell.

据了解，燃料电池和锂离子（聚合物）电池的区别是，前者将化学能转为电能，需要补充反应物。

燃料电池(FuelCell)是一种将存在于燃料与氧化剂中的化学能直接转化为电能的发电装置。燃料和空气分别送进燃料电池，电就被奇妙地生产出来。它从外表上看有正负极和电解质等，像一个蓄电池，但实质上它不能“储电”而是一个“发电厂”。简单地说就是利用化学反应电荷转移发电。这样应该就能解决容量问题，但问题是反应物的填充，就像需要加油站作支持一样，好处就是，用完补充就可以了。不用等待充电。
