Nanoengineering of a New Generation Proton Exchange Membrane for Micro Fuel Cells

Moghaddam S., Masel R., Shannon M., University of Illinois at Urbana-Champaign, US

We report development of the first viable silicon-based proton exchange membrane (PEM). This was achieved through self-assembly of 3-mercaptopropyl-trimethoxysilane (MPTMS) molecules inside extremely high aspect ratio torturous silicon nanopores. This development can greatly benefit the [...]

Self-assembly of Functional Groups inside High Aspect Ratio Silicon Nanopores

Moghaddam S., Masel R., Shannon M., UIUC, US

A novel technique has been developed to assemble molecules with functional end groups inside pores of a nanoporous silicon membrane. A 20-um thick p-doped silicon membrane was anodized in HF electrolyte to produce 5-7 nm [...]
