STATIONARY POWER – SOFC
• Higher sensitivity to operating costo Efficiencyo Fuel cost – natural gas preferred
• Data centers offer a large potential initial market
12
ON-HIGHWAY POWER – PEM OR SOFC• Higher sensitivity to initial investment
• Requires distributed fuel availability
• Sensitive to fuel price, but not as much as stationary power
