Abstract

Water electrolysis using proton exchange membrane (PEM) technology is a promising pathway
to generate hydrogen for energy applications because of the lack of corrosive
electrolytes, small footprint, and ability to generate at differential pressure, requiring
only deionized water and an energy source. Using a renewable energy source as the input
power enables a carbon-free cycle. In 2008, Proton created a cell stack roadmap to
leverage the material advancements made in fuel cells as well as address new design
requirements. The overall impact of this research to date has been considerable.
Efficiency improvements of 20% have been demonstrated for membrane and catalyst
configurations that have been tested to over 1000 hours. Cost reductions of over 15% of
the total stack cost have also been proven to be feasible. Additional pathways for the
next 3-5 years are expected to continue to make progress in reducing the cost of hydrogen
from water electrolysis.
