Fuel Cell System Modeling Simulation

GT-SUITE is the ideal platform for the analysis and optimization of fuel cell systems and their components


Combining industry leading productivity tools and collaboration features with advanced multi-physics modeling capabilities, GT-SUITE can be used throughout the entire product development process.

GT-SUITE integrates flow, thermal, chemical, and electrical solutions to enable complete modeling of the Balance of Plant and Vehicle Systems, such as air compression and humidification, hydrogen storage and recirculation, cooling systems, power management controls, and more.

The flexible range of fidelity provides an ideal simulation environment for system design, component selection, and controls optimization.


  • Modeling of any fuel-cell system configuration with GT-SUITE’s object-oriented model building architecture
  • Design and selection of components such as fuel cell stack, compressors, pumps, humidifiers, ejectors, heat exchangers, tanks, and more.
  • Optimization of water management, thermal, stoichiometry, and pressure controls.
  • Drive-cycle analysis for power management and battery sizing to ensure drivability, fuel economy, and reliability
  • Ability to operate at the proper combination of fidelity and speed to capture important transient effects, such as flooding, starvation, hot spots, and more.
  • Solver Features:
    • Compressible Navier-Stokes solution with real gas equation
    • Multiple species and multiple phases possible
    • Dynamic condensation and evaporation models
    • Time-accurate solver – required for transient analyses and control system development
    • Well-tested compressor and turbine map interpolation and extrapolation capabilities
