Fuel Cell Technologies Office Reaches Major Patent Milestone

Fuel cells are an emerging technology that can provide heat and electricity to buildings and power for vehicles while emitting nothing but water. The Energy Department’s Fuel Cell Technologies Office (FCTO) within the Office of Energy Efficiency and Renewable Energy, supports research and development (R&D) that improves the performance and lowers the cost of these systems. The office recently reached a major milestone, with 500 patents resulting from FCTO-supported R&D.
