Portable 1 kW hydrogen fuel cell module for motive and man-portable applications such as materials handling equipment, AGVs and construction equipment. It delivers 1 kW through-life power at 24–48 V and weighs approximately 10 kg.
The IE-POWER 1T and 1U is a 1 kW portable hydrogen fuel cell module made by Intelligent Energy for motive and man-portable applications. Supplied with hydrogen gas and air, it provides full rated power for as long as both are available, with zero-emission and quiet operation. The modules are offered in a range of configurations to match customer requirements.
The module is intended for distribution warehousing, manufacturing facilities and construction sites. Typical host equipment includes materials handling equipment, automated guided vehicles (AGVs), forklift trucks, mobile elevating work platforms (MEWPs), mobile lighting towers and portable fuel cell generators that provide flexible, off-grid power. Rapid refuelling and zero-emission operation are the stated advantages over battery and diesel power sources, and the module is positioned as a diesel replacement for construction equipment.
Through-life power is 1 kW, which sets the continuous load an integrator can plan for, and a maximum of 1.2 kW is given for configurations above 24 V. Output voltage is 24–48 V depending on configuration, so the module can be matched to the DC bus of the host machine. Rated current is up to 50 A at 24 V or below and is lower at 48 V, which determines cable and protection sizing. Hydrogen consumption is less than 70 g/kWh, which allows fuel use to be estimated for a given duty cycle. Mass is approximately 10 kg, and the maximum dimensions are listed in the specifications. The stated altitude range is 0–1,500 m and the operating ambient temperature range is 5–35 °C.
The U-Flow air management system allows the unit to be integrated and operated efficiently in confined spaces such as forklift trucks, MEWPs and mobile lighting towers, and a choice of airflow arrangements is available. The module is described as easy to integrate with all battery technologies, and the design is scalable. Hydrogen gas is the only fuel type. The full product specification is given in the manufacturer's datasheet.
The module is shock and vibration tested in all directions and has a wide environmental envelope for harsh environments where reliable power is needed all day. No regulatory certifications or standards are listed in the available product information, so integrators should confirm compliance requirements for their application with Intelligent Energy.
The stated benefits are minimal maintenance, a lower total cost of ownership, no power degradation, quiet operation and quick refuelling that increases productivity. The compact, portable format suits portable generators, AGVs and construction equipment that need dependable all-day power.
