In this work we report on the hydrogen production capacity of single-chamber microbial electrohydrogenesis cell (MEC) with optimized design characteristics, in particular cathode surface area and anode-cathode spacing using acetate as substrate. The results showed that the maximal H production rates and best energetic performances could be obtained using the smallest, 71 cm stainless steel cathode and 4 cm electrode distances, employing a 60 cm bioanode. Cyclic voltammetric analysis was employed to investigate the dominant electron transfer mechanism of the architecturally optimized system.
在本研究中，我们报告了具有优化设计特征的单室微生物电产氢电池（MEC）的产氢能力，特别是以醋酸盐为底物时的阴极表面积和阴阳极间距。结果表明，使用最小的71平方厘米不锈钢阴极和4厘米的电极间距，并采用60厘米的生物阳极，可获得最大产氢速率和最佳能量性能。采用循环伏安分析来研究结构优化系统的主要电子转移机制。
