Large scale development of fuel cells for means of transportation applications is a need for lowering carbon dioxide emissions. Hydrogen oxidation (anode side) and oxygen reduction (cathode side) lead to the production of electricity that could be used to power vehicles while releasing only water as byproduct.
For large scale applications of this technology, there is an urgent need of research development on catalytic materials, on their processing methods and on fuel cell electrode microstructuration.
PEFMC performance are closely related to multiphasic mass transport properties (gas: oxygen and hydrogen, liquid: water), heat transfer and electrical conductivity in fuel cell constituents, especially in the gas diffusion layer (GDL).
The various transport properties can be linked to the mechanical, morphological, microstructural and physical characteristics of the GDL and can be tuned depending on the materials used or the processing methods.
The main goal of this internship is to build and test new GDL architectures on the base of a 3D printed skeleton. This printing technology should ease layer structuration that will improve gas transport within the device. The objective is to validate this new approach in the fabrication of GDL.
Main tasks to develop these new architectures during this work:
-Thin layers fabrication using large scale deposition methods
-Carbon ink formulations for microporous layer preparation
-PEFMC assembly with the new materials and device electrical characterization
