制备了一种微光合电化学电池（/spl mu/PEC），并对其作为移动MEMS器件（如遥感器）的潜在自维持电源进行了测试。/spl mu/PEC利用蓝绿藻的自然代谢过程（光合作用和呼吸作用）将光能转化为电能。在光照和黑暗条件下，/spl mu/PEC产生的开路电位均超过400 mV，电流密度超过30 /spl mu/ a/ cm/sup 2/，负载为10-/spl ω /，功率密度为61 /spl mu/W/L。这些结果通常与Chiao等人（2002）的微型制造微生物燃料电池相当，尽管低于微型太阳能电池和宏观mfc和pec的结果。然而，与太阳能电池不同的是，/spl mu/PEC具有在黑暗中发电的能力；与甲醇或微生物燃料电池不同，它不需要燃料。
A micro photosynthetic electrochemical cell (/spl mu/PEC) was fabricated and tested as a potential self-sustained power source for mobile MEMS devices such as remote sensors. The /spl mu/PEC harnesses the natural metabolic processes (photosynthesis and respiration) of the blue-green algae Anabaena to convert light energy into electrical power. In both light and dark conditions, the /spl mu/PEC produced an open-circuit potential of over 400 mV, a current density of over 30 /spl mu/A/cm/sup 2/ with a 10-/spl Omega/ load, and a power density of 61 /spl mu/W/L. These results are generally comparable to the microfabricated microbial fuel cell by Chiao et. al. (2002), though lower than those of micro solar cells and of macroscale MFCs and PECs. However, unlike solar cells, the /spl mu/PEC has the ability to produce power in the dark; and unlike methanol or microbial fuel cells, no fuel is required.
