生物电化学系统（BES）对于能源和化学品的可持续生产有着巨大的前景。本综述讨论了 BES 实际应用所必需的因素。首先，我们将效益（产品价值和废水清洁）与成本（资本和运营成本）进行比较。在此基础上，我们分析了使微生物燃料电池（MFC）和产氢微生物电解电池（MEC）具有成本效益所需的最大内阻（以mO?m2为单位）和电流密度。我们将这些最大电阻与报告的内阻和电流密度进行比较，特别关注阴极电阻。虽然MFC的电流密度仍需要大幅增加（即需要降低内阻），但MEC更接近应用，因为可以通过增加施加的电压来增加其电流密度。对于MFC来说，将高价值产品的生产与电力生产和废水处理相结合是一条有前途的途径。
Bioelectrochemical systems (BESs) hold great promise for sustainable production of energy and chemicals. This review addresses the factors that are essential for practical application of BESs. First, we compare benefits (value of products and cleaning of wastewater) with costs (capital and operational costs). Based on this, we analyze the maximum internal resistance (in mO?m2) and current density that is required to make microbial fuel cells (MFCs) and hydrogen-producing microbial electrolysis cells (MECs) cost effective. We compare these maximum resistances to reported internal resistances and current densities with special focus on cathodic resistances. Whereas the current densities of MFCs still need to be increased considerably (i.e., internal resistance needs to be decreased), MECs are closer to application as their current densities can be increased by increasing the applied voltage. For MFCs, the production of high-value products in combination with electricity production and wastewater treatment is a promising route.
