Determination of developing trend for a novelty microbial electrolysis cell by a modified inventive problem solving approach

Nowadays, the design of waste treatment needs to be environmentally-friendly. Due to the fact that the concern of global warming is getting critical, the reuse of waste treatment can be beneficial in reducing carbon dioxide emission. Microbial electrolysis cell (MEC) is a device that can reduce the organic materials and produce the green energy, biohydrogen. Therefore, MEC provides an alternative path for waste degradation. In this study, MEC was analyzed with TRIZ that aims to eliminate contradiction matrix from the analysis in order to improve the MEC efficiency. The study approach is based on the following steps: classifying patents and paper, determining engineering parameters; solving the contradictory problems with 40 innovative principles, and finding the solutions. The results were verified by the currently researches.
