There are people who are mimicking the energy-harvesting device inside of purple bacterium, the people at ASU. Even more interesting, lately, in the last couple of weeks, people have seen that there's an enzyme called hydrogenase that's able to evolve hydrogen from proton and electrons, and is able to take hydrogen up -- basically what's happening in a fuel cell, in the anode of a fuel cell and in a reversible fuel cell.
现在有些人在模彷紫色细菌体内 能源采集装置 这些人来自亚力桑那州立大学 更有趣的是， 不久以前，有人发现 一种叫做氢化酵素的东西， 它能够利用质子跟电子来产生氢气 也能够分解氢气 基本上说这就是燃料电池内部的反应：在燃料电池的阳极 以及在可转换的燃料电池的反应。
