This talk will give an introduction of the state-of-art micro solid oxide fuel cells (micro-SOFCs) using silicon-based micromachining technology to achieve a breakthrough increase in lateral dimension of such electrochemical energy conversion devices. The lateral dimension of the nanoscale thin film electrolyte membrane, which the thickness is only tens of nanometer, has been chronically limited to only hundreds of micrometers scale due to the fragile thin oxide membrane. Through our unique design from the mechanics approach to relieve the stress level of the membrane, and with the help of a simple combinatorial etching process, the lateral dimension of the micro-SOFCs electrolyte membrane was increased to several millimetres scale. The technology breakthrough introduced here can further the practical application of such promising device closer to commercial manufacturing stage in the area including unmanned aviation vehicles (UAVs) or military drones. 

In addition to the fuel cell research, I will also give an overview of our work on 4D printing, as well as the activities in Singapore 3D printing center.
