微生物燃料电池（MFC）中的微生物在消耗电子供体的同时释放电子。在厌氧阳极室中，利用底物如碳水化合物，结果在MFC中产生生物电。MFC可以用作小型设备如生物传感器中的发电机。MFC仍然面临着实际的障碍，如低发电功率和电流密度。最近，由于MFC能够在温和条件下运行并使用不同的可生物降解基质作为燃料，因此受到了人们的广泛关注。MFC由阳极室和阴极室组成。活性微生物被积极地分解代谢为碳源，因此产生生物电。产生的电子被传输到阳极表面，但产生的质子必须通过质子交换膜（PEM）才能到达阴极室。质子交换膜作为影响MFC发电的关键因素，在这里进行了研究，并充分讨论了它的重要性。
Microorganisms in microbial fuel cells (MFC) liberate electrons while the electron donors are consumed. In the anaerobic anode compartment, substrates such as carbohydrates are utilized and as a result bioelectricity is produced in the MFC. MFCs may be utilized as electricity generators in small devices such as biosensors. MFCs still face practical barriers such as low generated power and current density. Recently, a great deal of attention has been given to MFCs due to their ability to operate at mild conditions and using different biodegradable substrates as fuel. The MFC consists of anode and cathode compartments. Active microorganisms are actively catabolized to carbon sources, therefore generating bioelectricity. The produced electron is transmitted to the anode surface but the generated protons must pass through the proton exchange membrane (PEM) in order to reach the cathode compartment. PEM as a key factor affecting electricity generation in MFCs has been investigated here and its importance fully discussed.
