Fuel Cell H2/O2
H-TEC's Fuel Cell H2/O2 is a single-cell Proton Exchange Membrane Fuel Cell (PEMFC) for hydrogen and oxygen operation. Running your fuel cell on pure Oxygen versus just Atmospheric Oxygen (Air) will provide a much higher performance with greater results!
Double Fuel Cell H2/O2
H-TEC's Double Fuel Cell H2/O2 is a double-cell Proton Exchange Membrane Fuel Cell (PEMFC) for hydrogen and oxygen operation. Running your fuel cell on pure Oxygen versus just Atmospheric Oxygen (Air) will provide a much higher performance with greater results!
Double Fuel Cell H2/O2/Air
This Proton Exchange Membrane (PEM) fuel cell produces electricity by using hydrogen and oxygen gas (or atmospheric oxygen). Its only by-products are water and heat.
Quattro Fuel Cell H2/O2/Air
This Proton Exchange Membrane (PEM) fuel cell produces electricity by using hydrogen and oxygen gas (or atmospheric oxygen). Its only by-products are water and heat.

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).

PFSA D170-U Proton Exchange Membrane
PFSA D170-U Proton Exchange Membrane (PEM) is used to separate the anode and cathode compartment of PEM water electrolyzers because of its relatively thick nature (~170 microns or 7-mils or 0.007 inches) and robustness compared to other thinner PFSA membranes. This is an unreinforced (also known as self-supporting)...
PFSA D125-U Proton Exchange Membrane
PFSA D125-U Proton Exchange Membrane (PEM) is used to separate the anode and cathode compartment of PEM water electrolyzers because of its relatively thick nature (~125 microns or 5-mils or 0.005 inches) and robustness compared to other thinner PFSA membranes. This is an unreinforced (also known as self-supporting)...
PFSA D50-U Proton Exchange Membrane
PFSA D50-U Proton Exchange Membrane (PEM) is used to separate the anode and cathode compartment of PEM fuel cell stacks that usually consume H2/Air as the fuel/oxidant and requires high current density operations with long lifetime (which necessitates the use of a relatively thin membrane). It is quite a common...
