摘要
生物质燃料电池与生物制氢技术正在飞速发展.生物质燃料电池在有机废物和废水的处理领域非常实用,可以将有机物转化成生物质能源,用来处理生活有机垃圾和废水.近期,世界最新研究领域之一的便是在生物质反应器中接种光合细菌和氢化细菌,并使之能够与生物质燃料电池相结合,利用监控系统来控制生物反应器和生物质燃料电池的反应.本试验的目的是在可变操作条件下测试生物反应器和生物质燃料电池(PEFC)联合系统的产流能力.嗜温梭菌是由牛粪中分离出并接种到反应器中生产氢气,氢气的产生由微型气相色谱仪测定,当氢气浓度达到80%视为达到稳定状态.生物质燃料电池在较低的压力下进行,在高于3 k Pa的环境中产生稳定的电流3.5 m A和稳定的电压0.65 V,平均发电量为25 W.同时,用有限元分析了阳极上的氢浓度分布.
The technologies of bio-hydrogenation and biofuel cell are developing rapidly. In waste and waste-water treatment,bio-fuel cell can be a practical technique for the conversion of organic matter into biomass energy while bio-reactors can treat domestic organic waste and waste-water. The bio-reactor is seeded with photo-synthetic or hydrogenation bacteria, and is able to couple with a bio-fuel cell which is one of the hottest research areas in the world, presently. Using a monitoring system controls the bio-reac- tot and bio-fuel cell processes. The objective of the present experiment was to test the amperage and voltage production capability of a bio-reactor coupled with a bio-fuel cell （ PEFC ）, operated under varia- ble conditions. The mesophilic clostridium sp. was isolated from cow manure and then used as inoculum to seed the bio-reactor for hydrogen production which was measured by Micro GC. The hydrogen con- centration exceeded over 80 %, when steady state was reached. The bio-fuel cell operated under a lower pressure of 3 kPa above atmosphere and generated a steady state current and voltage of 3.5 mA and 0. 65 V. The mean power generation was 25 W. The finite element analysis method was employed to calcu- late the hydrogen diffusion in the anode. The system was able to function using highly concentrated or- ganic waste-water.
