Abstract

This study describes the work carried out towards the optimization of critical MFC components with potential 3D fabricated materials. The response of the optimised fuel cells, which were fed with soft materials such as gelatin, alginate and Nafion™, is also reported. The optimised components were the membrane and the cathode electrode. Membrane was substituted with a custom made terracotta sheet and the electrode used was a single sheet of carbon veil coated with an activated carbon paste. The results showed that amongst the soft materials tested, gelatin performed better; also it revealed that even after a 10-day starvation period the gelatin had better longevity. These results show that MFCs can be potentially 3D-printed monolithically using the EvoBot platform.
