采用填充床阳极的甲醇生物燃料电池

Study of the Biofuel Cell Based on Methanol Using the Packed Bed Anode

燃料电池是将化学能转变为电能的装置,人们已经在无机物燃料电池方面取得了很大进展。现在以各种有机物为燃料的生物燃料电池受到了重视。自然界存在大量的微生物和酶,可以氧化各种有机物,因此在原理上可以构建许多采用天然原料为燃料的生物燃料电池。目前,生物燃料电池实用化的主要问题是所提供的电流密度低,通过使用介体可以提高电流密度,在这方面已经做了许多工作。

A packed bed anode was successfully used in biofuel cell with thionine as re-dox mediator and alcohol oxidase as biocatalyst. The graphite particles was used for the packed bed anode. With the use of a three-dimensional packed bed anode, a rapid increase in the electricity output was observed.
