Abstract

Herein, a simple wireless charger which provided an alternative to conventional connection for delivering the electricity was employed to power the microbial electrolysis cell (MEC) for hydrogen recovery from organics. The coulombic efficiency of the wireless power transmission (WPT) was 75.37%, which was nearly similar to the average value of the conventional wired power transmission (CWPT) at the same experimental conditions (78.23%). The energy efficiency was 130.58%, it was clearly that the wireless charging (141.57%) slightly resulted in energy losing compared with conductive wire connection. The saving cost of WPT-driven MEC was a promising compensation to the energy loss according to the economic analysis of WPT, i.e., the WPT can be cost-beneficial once the distance between charger and reactor beyond a limited value. Overall, the feasibility of WPT suggests a straightforward way to construct large-scale MES with low cost and comparable performance.

摘要

在此，采用一种简单的无线充电器为微生物电解池（MEC）供电，以替代传统的电力连接方式，从而从有机物中回收氢气。无线电力传输（WPT）的库仑效率为 75.37%，几乎与相同实验条件下传统有线电力传输（CWPT）的平均值（78.23%）相同。能量效率为 130.58%，显然与导电丝连接相比，无线充电（141.57%）略微导致能量损失。根据 WPT 的经济分析，WPT 驱动的 MEC 的节省成本是对能量损失的有希望的补偿，即一旦充电器和反应器之间的距离超过一个有限值，WPT 就可以具有成本效益。总的来说，WPT 的可行性表明了一种构建具有低成本和相当性能的大规模 MES 的简单方法。
