This work presents the use of non-commercial software for the design and development of a multiphysics model for some aspects of a proton exchange membrane fuel cell’s (PEMFC) operation and performance. Developing the model this way gives users greater freedom to adjust and improve upon the model than with common commercial modeling software packages. By using the non-commercial partial differential equation (PDE) solver FreeFem++, which utilizes a high-level programming language based on C++, we developed a model in which the set of equations representing the mechanisms that govern PEMFC operation and the algorithms for solving it can be freely tweaked, updated or overhauled by users. We discuss our choice of software and describe the advantages and limitations of our modeling approach, such as the flexibility provided by its open nature at the cost of added programming complexity compared to commercial packages. We also note how the geometry of the cell being modeled can easily be controlled through a set of user-defined parameters, or scripted to change for successive model runs as part of an optimization procedure or sensitivity analysis. We present results from a two-dimensional model for the cathode side in order to demonstrate the practicality of this approach.

The Relationship

Pressure drop on the cathode side of a PEM (Proton Exchange Membrane) fuel cell stack has been studied and used as a diagnostic tool. Since the Reynolds number at the beginning of the flow field channel was <250, the flow through the channel is laminar, and the relationship between the pressure drop and the flow rate is linear. Some departure from linearity was observed when water was either introduced in the stack or produced inside the stack in the electrochemical reaction. By monitoring the pressure drop in conjunction with the cell resistance in an operational fuel cell stack, it was possible to diagnose either flooding or drying conditions inside the stack.

Abstract Proton exchange membrane fuel cells (PEMFCs) based on syngas are a promising technology for electric vehicle applications. To increase the fuel conversion efficiency, the low-temperature waste heat from the PEMFC is absorbed by a refrigerator. The absorption refrigerator provides cool air for the interior space of the vehicle. Between finishing the steam reforming reaction and flowing into the fuel cell, the gases release heat continuously. A Brayton engine is introduced to absorb heat and provide a useful power output. A novel thermodynamic model of the integrated system of the PEMFC, refrigerator, and Brayton engine is established. Expressions for the power output and efficiency of the integrated system are derived. The effects of some key parameters are discussed in detail to attain optimum performance of the integrated system. The simulation results show that when the syngas consumption rate is 4.0 × 10−5 mol s−1cm−2, the integrated system operates in an optimum state, and the product of the efficiency and power density reaches a maximum. In this case, the efficiency and power density of the integrated system are 0.28 and 0.96 J s−1 cm−2, respectively, which are 46% higher than those of a PEMFC.
