Low-Cost and Light Bipolar Plates of PEM Fuel Cell

Excerpt

A composite material comprising Nylon-6 and S316L stainless steel alloy fibers to be fabricated bipolar plates is studied. The PEMFC plates are fabricated via an injection molding process, which yields better production rates than coating or treating metal plates with a suitable surface material. It is shown that the developed composite material has a suitable combination of properties and processability for PEMFC bipolar plate applications. Specifically, the chemical and electrochemical properties of the plates are found to be stable, and the plates demonstrate good anti-corrosion characteristics, resulting in an enhanced electrical conductivity, a stable cell performance, and an extended cell life.
