Hydrogen production was evaluated in two-chamber microbial electrolysis cells (MEC), where the chambers of the cell were separated using a new economical and environmentally friendly membrane made of poly (vinyl) alcohol/chitosan (PVA/CS). The MEC performance was compared to that of Nafion. The obtained results indicated that the MEC performance for hydrogen production did not show significant differences between the PVA/CS and Nafion membranes. MEC with PVA/CS showed the hydrogen production rate and hydrogen yield of 1277 ± 46 mL HLd and 974 ± 116 mL H g, respectively. The PVA/CS membrane allowed acetate removal that was 7% higher than that of Nafion due to the lower pH gradient and a lower voltage drop that increased the ion transfer across the membrane.
在双室微生物电解池 (MEC) 中评估了氢气的生成，其中使用了由聚乙烯醇/壳聚糖 (PVA/CS) 制成的新型经济环保膜将电池的腔室隔开。将 MEC 的性能与 Nafion 进行了比较。结果表明，PVA/CS 膜和 Nafion 膜之间的产氢性能没有显著差异。PVA/CS 膜的 MEC 表现出 1277±46 mL HLd 的氢气产生速率和 974±116 mL H g 的氢气产率。由于较低的 pH 梯度和较低的电压降，PVA/CS 膜允许去除的乙酸比 Nafion 高 7%，这增加了离子在膜中的传递。
