Components
50 W fuel cell stack
Designed for hydrogen-air operation the fuel cell stack includes 10 fuel cells generating 50 W maximum power output at 5 V DC. An integrated fan supplies the stack with oxygen and cools the system.
Controller board
The controller board ensures control and operation of the stack and protects the system from overloads and short circuits. An integrated RS232 interface enables visualization and processing of operating parameters via the included software.
Accessories
Hybrid extension kit
This supplementary set enables the design of a fuel cell hybrid system. The DC converter contains an integrated charge controller for 12 V lead batteries. Therefore, it is also possible to operate 12 V consumers independent of the output of the fuel cell.
H2 leak detection set
A hydrogen sensor for monitoring the workplace and testing for leaks, in addition to a special leak test liquid ensure maximum safety during use of the system.
H2 flow meter
The hydrogen flow meter enables the exact measurement of the current hydrogen consumption. The data connection is established via the controller board. The measured values can be displayed via the included software.
Software
The operation of the Constructor fuel cell system can be monitored and controlled with the included software. It enables the visualization and measurement of different essential system parameters:
- Stack voltage (V)
- Stack current (A)
- Stack temperature (°C)
- Fuel flow (ml/min)
- Fan power (%)
Hydrogen Supply
H2 Metal hydride canisters
The low-pressure metal hydride canister allows for safe and easy intermediate storage of hydrogen in compact form. An integrated quick coupling ensures the safe connecting and disconnecting. Available in three sizes: 60, 250, 760 Nl.
