H2 ECOnomy’s Gas Control Units (GCU) are designed for testing hydrogen/oxygen or hydrogen/air fuel cells, including the measurement and control of the pressure, mass flow, temperature and humidity of the H2 and O2 or Air.

GCU features include:

• GCU gas control units are equipped with devices for measuring and controlling gas flow rates, pressures and temperatures, as well as with humidifiers with ramped heating temperature regulation and a bypass line, allowing operation with or without humidification.

• The hydrogen channel can be set to be purged with specified intervals and duration, to help avoid flooding of the tested fuel cell when necessary.

• GCU is operated and controlled manually, by a dial, knobs and handles on the front panel. Once set, the system will maintain the gas temperature and humidity automatically.

• The unit has self-diagnostic capabilities to automatically fix some of the possible failures of its microprocessor program that may occur due to the proximity of powerful external sources of electromagnetic impulses.

• An optional PC interface with RS-232 protocol (through a COM port) can be added for a small additional fee to enable reading, displaying and recording the test data on a personal computer using the National Instruments LabVIEW™ based Automated User Monitoring Interface (AUMI) software.

• Designed to fully comply with safe operation requirements, protecting personnel from electric shock, fire and explosion.

• All sensors in the GCU Gas Control Units are spark-protected to ensure the safe operation with flammable gases.

• A special hydrogen safety sensor to detect the presence of as low as 0.5% of leaked hydrogen in the unit, with light and sound alarm indication and automatic shutdown. The Alarm indication is also duplicated in the AUMI software interface.

• In case of necessity, both channels can be connected to nitrogen or inert gas supply source.
