LEAF的动力来源主要通过内置在自身叶片顶棚里的光硒电池（它自己的这个位置朝向太阳收集并储藏更多的能量）在此期间在轮子内部微小的涡轮机通过风产生电能并储藏在它自己的蓄电池组里供应能量给微生物燃料电池。

According to the experimental results, both the conducting area and material of current collector slices have great influence on the performance of micro PEMFC, especially the former one. The increment of cell's performance is finite by increasing the gas reheats temperature. The performance is better for open ratio 75% compared with 50% and 67%. The concentration polarization is improved by increasing the air flow rate at high current density and if the GDL diffusive capability in the latter cell could be promoted, the differences between these two cells' performances would be reduced.

由实验结果可知，集电片的导电面积与材料对於电池性能有显著的影响，尤其是前者；对於增加反应气体的再热温度，微型燃料电池增加的性能有限；双极板开孔率75%相较於开孔率为50%与67%有最佳的性能曲线；增加阴极气体空气的流量，可以改善高电流情况下的浓度极化现象，所以若我们能增加气体扩散层的扩散能力，则可以减少两者的性能差距。

Aiming at the question of low output and high cost, a two-chambered microbial fuel cell based on the mechanism of microbial metabolism and electron transfer processes was coustructed.

熔融碳酸盐燃料电池在开始运行初期，承受一定负荷的多孔镍在转化为多孔氧化镍阴极的过程中往往会受到较严重的形变破坏，对电池的使用性能和寿命造成不良影响。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
