• To demonstrate RFC technology (fuel cell + electrolysis) as an effective energy storage option for renewable energy systems based on power generation from solar or wind sources.

PV Panels

Features:

• The 1-kW trailer photovoltaic (PV) panels to generate electric power, which can be used directly by various loads (12 volts DC or 110 volts AC); excess power is fed to an electrolyzer that converts water into hydrogen and oxygen; the hydrogen is stored for subsequent recombination in a fuel cell, providing the same electric power to the various loads.

Benefits:

• RFC energy storage is quiet, efficient, environmentally benign, and offers tremendous flexibility because the power and energy portions of the system are independent of one another
• Effectively demonstrates the transition from a fossil fuel economy to a hydrogen economy

Applications:

• Off-the-grid power systems, remote stand-alone power systems, uninterruptible power supplies, and emergency power systems.
