HBox - A passive hydrogen generator suitable for a wide variety of applications

HBox is based on a novel high efficiency proton-exchange membrane (PEM) electrolyser and is available in three formats:

HBox 3000
Producing 3000 cc/min H2 at 15 bar
HBox-PV
For direct coupling to a PV array of up to 1,300W peak power output, producing 20-40 kg H2 per annum (depending on site latitude, climate, orientation and tilt).
HCore
Bare unit for hydrogen system integrators producing up to 3000cc/min H2 at 15 bar

The HBox range has been designed for hydrogen system integrators, fuel cell developers and experimenters. HBox is suitable for charging standard cylinders and hydride stores.

Key Features

Simple to use
Failsafe
Silent operation
Passive water/gas separation
Passive cooling of electrolyser cells
High efficiency
Negligible auxiliary power requirement
Robust construction

In particular, HBox-PV provides an off-grid solution for those interested in generating truly “green” hydrogen for charging hydrogen stores in stationary applications (including solar hydrogen homes and back-up power applications).
