Development of a 50 kW, high efficiency, high power density, CO-tolerant PEM fuel cell stack system

摘要

Honeywell has been developing a 50-kW net proton exchange membrane (PEM) fuel cell stack system for transportation applications. The stack system is comprised of a PEM fuel cell stack and supporting gas, thermal and water management subsystems and is capable of integration with a number of fuel processors. The present effort focuses on system design and analysis, stack technology development, and fabrication and testing of 10-kW class stacks leading to the demonstration of a 50 kW brassboard system. This paper summarizes the status of the PEM technology being developed at Honeywell.
