Heavy-duty PEM fuel cell module in a modular one-box design for buses, trucks, rail, marine and off-highway equipment. It delivers 110 kW of through-life net power and weighs 285 kg, excluding condenser and DC-DC.
The IE-DRIVE HD100 is a heavy-duty PEM fuel cell module, a hydrogen fuel cell system made by Intelligent Energy for zero-emission power in demanding ground and marine applications. It is a modular one-box unit for buses, trucks, rail, marine vessels, off-highway and construction equipment, material handling and stationary installations. The manufacturer designed it for heavy-duty use and states that it delivers compact, modular systems with fewer components, improved reliability and reduced system costs.
The module uses Intelligent Energy's patented evaporatively cooled (EC) PEM stack technology. According to the manufacturer, this approach removes the need for bulky radiators and complex thermal management systems, which suits space-constrained and weight-sensitive installations. Bipolar plates reduce stack size and weight, and the design includes a smaller heat exchanger. The manufacturer also cites improved transient response without accelerated stack ageing, and a simpler system architecture with less balance of plant for the same level of performance.
The electrical and physical figures show how the module fits a powertrain. Through-life net power is 110 kW, the output figure to use when sizing the system over the service life of the module. The output voltage range is 250–400 V and the net current output reaches 440 A, so the DC bus or DC-DC converter must accept that window. Mass is 285 kg and the module dimensions are 1260 × 700 × 520 mm (L × W × H). The mass and dimensions exclude the condenser and the DC-DC converter, so weight and installation space must be budgeted for both separately.
The main parts are housed in a modular plug-and-play unit, which the manufacturer describes as simple to integrate and scalable to multi-megawatt systems. Operating ambient temperature is -20–40 °C nominal, and the module also has a derated operating range beyond those limits, so the thermal design of the host vehicle or enclosure should account for reduced output at temperature extremes. The source documents do not specify hydrogen supply pressure, communication interfaces or ingress protection, which should be confirmed with the manufacturer before integration.
The datasheet lists no certifications or standards for the module, so approvals for a given vehicle or site must be agreed with the manufacturer. Intelligent Energy builds its fuel cell systems in the UK.
Typical applications are buses and trucks, off-highway and construction equipment where emissions and noise restrictions apply, material handling, marine propulsion and auxiliary power, rail as a zero-emission alternative to diesel locomotives, and stationary power for off-grid or backup use.
