We offer PEMFC single cells at 1 cm2, 5 cm2, 25 cm2, 50 cm2 and 100 cm2 active area with Poco graphite monopolar plates in serpentine, column, straight channel or interdigitated flow patterns. The cell comes with gold coated copper current collectors, heating mats if required and a conditioned MEA with gaskets.

If you require a custom single cell PEMFC design or a single cell for electrolyser or flow battery applications please contact us.

We can provide air or water cooled 7 cell stack with 50cm2 active area of serpentine, straight channel or interdigitated flow pattern with an energy rating of ~50W. Custom stacks of this design are available up to 20 cells, contact us for further details.

We also have air cooled 2, 5, 10 or 18 cell PEMFC stacks ranging from open-circuit voltages (OCV) of 1.9V, 4.9V, 9.8V and 18V, respectively, and water cooled PEMFC stacks with power ratings of 500W or 1000W.

We can provide BoP parts such as; back pressure regulators, back pressure control modules, moisture traps, pressure sensors, mass flow controllers, mass flow meters, PID temperature controllers, stack humidifiers, flexible stainless steel insulated and heated gas transfer lines, flat silicon or rod heaters and much more, contact us.

We offer a complete fuel cell test system ranging from 125W, 500W or 1000W with optional modules for various diagnostics and control systems, e.g. potentiostat, temperature and stack monitoring and back pressure control.
