Reversible Fuel Cell H2/O2/Air

The RFC H2/O2/Air is a Reversible Fuel Cell (RFC), meaning it can work in either electrolysis or fuel cell mode. As an electrolyser, it uses an external voltage to break down water into hydrogen and oxygen. As a fuel cell, it produces electricity by using hydrogen and oxygen gas (or atmospheric oxygen, also known as air).

Description

Description

H-TEC's educational Reversible Fuel Cell (RFC) H2/O2/Air Reversible Proton Exchange Membrane Fuel Cell (PEMFC) can be operated in three different modes:
(1) Electrolyzer Mode - Uses external voltage to produce Hydrogen and Oxygen
(2) H2/O2 Fuel Cell Mode - Uses pure Hydrogen and Oxygen to produce electricity
(3) H2/Air Fuel Cell Mode - Uses pure Hydrogen and Atmospheric Oxygen (also known as air) to produce electricity

 Reversible Fuel Cell (RFC) H2/O2/Air, R103 - Technical Specifications:
• Hydrogen Production in Electrolyser Mode: 7mL/min
• Oxygen Production in Electrolyser Mode: 3.5mL/min
• Power in Fuel Cell H2/O2 Mode: 500 mW @ 750mA
• Power in Fuel Cell H2/Air Mode: 200 mW @ 300mA
• Dimensions (H x W x D): 2" x 1.6" x 2.2" (50 x 40 x 57 mm)
• Weight: 1.8 oz (52 g)
