2. Objective
• Perspective from providers of small, portable PEM fuel cell
power systems
• Relationship between successes in small fuel cell system
markets and the enhancement of future, more challenging
markets for larger systems.
• How this can be aided by DOE supported R&D in hydrogen
storage systems, combined with the market-driven maturation of
system components.
3. First-markets-first premise
• Hydrogen will be a key element in a long-term, secure, sustainable
energy economy.
• Small fuel cell systems can accelerate the commercialization of
component technologies that will be needed for automotive and
larger applications.
• Early revenue from selling products with 1cm2, 100 cm2, 1000cm2
of MEAs and bipolar plates will necessarily improve component
performance, cost and service life, in turn benefiting future
automotive and larger applications requiring 200,000cm2 each.
• Energy supply is critical to success of small fuel cell systems, and
as such any improvement in hydrogen storage technologies can
have a corresponding increase in market growth for the systems.
4. Paths of least
Early markets and startup companies
need to find lowest resistance paths to
profitability.
Lowering the difficulty in providing new
fuel cell products helps in defining early
products and applications.
5. Potential market area for fuel cells (or
other power plants).
Defined by peak power vs. cost per unit
power capacity (W vs. $/kW) for typical
applications currently satisfied by legacy
technologies.
