PEM fuel cell stacks



Fuel cell systems available from 30 Watts to 100 Watts, designed for easy system integration.
Based on an open-cathode PEM fuel cell architecture, the system offers good power densities, minimum balance-of-plant requirements and simplicity of operation.
The fuel cell controller is equiped with on-board measurements and analog transmission. When the fuel cell is integrated into an application, operating data can be collected directly from the controller. Additional sensors can be plugged to the controller board.

Fuel cell stacks and electronic controllers can be sold separately.


– Robust open-cathode fuel cell design
– No external power source required (electronics powered by the fuel cell)
– Datalink port on controller board
– Available free input channels on controller for sensors or control
– led display on controller board for system state indication
– Open-source embedded microcontroller code
– Code and functunalities can be taylored by the user for system integration.
