Residential proton exchange membrane (PEM) fuel cells are in the precommercial stages of development, and limited field testing and demonstrations have been performed to date. This paper provides an overview of the Department of Defense (DOD) Residential PEM Fuel Cell Demonstration Program, as well as an in-depth case study of the ten PEM fuel cells installed at a military facility in New York as part of this program. The installation, operation, performance, and benefits of these units are presented in this paper, along with lessons learned from the demonstration.
