Outline of Final Research Achievements

In order to use a bio-fuel cell or a self-driven coulometry device as a teaching material, we made disposable type electrochemical cells and developed an inexpensive device. The bio-fuel cell we made succeeded in driving the model motor for about an hour. In addition, we introduced various enzymes into a self-driven coulometry device and succeeded in developing a method for measuring food components such as glucose and pyruvic acid etc. which contained in Sake mash and various foods. Furthermore, a rapid extraction method for enzymes contained in malted rice was established using an easily available device. These devices can be used at the high school and technical college level, and we developed an experimental curriculum by using it as a teaching material.
