3D Printed Membraneless Electrochemical Devices

We are sorry, this position has been filled.

This project will involve the design and development of novel membraneless electrochemical devices for the conversion of electrical energy into chemical energy. These electrolyzers are very important for a clean energy future because they can use electricity generated by renewable solar or wind resources to produce storable chemical fuels such as hydrogen. This project will be experimental in nature, focusing on the design of devices, fabrication of devices, and evaluation of their performance. Conventional electrolyzers rely on membranes, which are costly and can be prone to failure. The goal of the project is to develop new electrolyzers based on flow-through electrodes that do not require membranes, and therefore have potential to have substantially lower cost than conventional electrolyzers. 3D printing, or additive manufacturing, will be used to fabricate the electrolyzers. Electroanalytical techniques and in situ high speed video analysis will be employed to evaluate device performance under different operating conditions and electrode configurations.
