Proton Exchange Membrane (PEM) Fuel Processor

"We put the fuel in fuel cells®"

PCI is developing an integrated fuel processor for liquid fuels for application in PEM and High Temperature PEM fuel cell systems. Building upon its ultra-compact fuel reformer and fuel reforming catalytic reactor technologies, PCI is optimizing its fuel reformer and fuel processor technologies for the size, weight and performance needed to enable liquid-fueled PEM fuel cell systems under multiple Army and Navy programs.

PCI's Microlith®; Compact Logistics Fuel ProcessorTM System for High Temperature PEMs and PEMs consists of an integrated fuel/air/steam injector, autothermal reformer (ATR), heat exchanger, sulfur trap and water gas shift reactor. The system is designed to take in medium sulfur fuel (<400 ppm sulfur) and provide reformate with <1 ppm sulfur for use in a high Temperature PEM or with additional CO cleanup for use in a low temperature PEM fuel cell.
