Fuel Cells modeling based on LIBPF®
The LIBPF® FC (Fuel Cell) module is an extension to LIBPF® to support fuel cell and fuel cell system modeling.
The development of this module was supported from Università di Genova's PERT group.
With respect to the core modeling features of LIBPF®, the LIBPF® FC adds:
- Distributed parameters unit operations: generic multi-stage 2-D unit, with spiral, co-, cross- or counter-flow pattern;
Fuel cell model with 2 or more streams, each supporting multiple equilibrium or fixed conversion reactions; one or more electrochemical reactions supported.
Steady state simulation of fuel cells as well as fuel cell power generation systems
Detailed 2D simulation of fuel cell, supports co-flow, cross-flow, counter-flow, spiral flow patterns
Simplified simulation of fuel cell, supports voltage correction maps to reproduce results of detailed model
- Reactive heat exchangers with equilibrium or partial equilibrium reactions
Detailed 2D Simulation of the Fuel Cell
Sample solid temperature field for an industrial-size MCFC (Molten Carbonate Fuel Cell):
Supported flow patterns
The flow pattern of the anode and cathode gases can be set easily using a simple symbology, whereby:
|the blue color indicates a source is located in the cell
|the red color indicates a sink is located in the cell
|the arrows indicate the direction of the flow coming out of the cell
An example of cross-flow pattern:
An example of co-cross-flow spiral pattern:
Simulation of fuel cell power generation systems
Static or dynamic simulation of entire fuel cell power generation systems can be performed with LIBPF®. All key unit operations are modeled, including reactive heat exchangers, compressor, fuel cell; typically with a concentrated parameters approach.
