The following release note provides a short summary of the main highlights of this release. More specific details can be found in the product release notes of AVL CRUISE M and AVL FIRE M.

PEM Fuel Cell System Layout and Integration

Reduced Dimensionality PEMFC Model

The latest version of CRUISE M includes a new electrochemical model for proton exchange membrane fuel cell (PEMFC) simulation. The model covers the relevant physical domains of the stack and their interactions. This includes, for example, anode and cathode gas flow, electric network, and thermal network, as well as the electrochemical and transport processes in the membrane electrode assembly (MEA). With regards to channel flow direction, the domains are discretized in 1D while the MEA-related electrochemical and transport models feature a reduced dimensionality approach. The latter offers an optimum compromise between modeling depth and computational performance, with the underlying models ensuring full consistency in consideration of thermodynamics and electrochemistry.

The Reduced Dimensionality PEMFC Model consistently correlates cell performance with reactant concentrations, temperature, water content and current, and thus holds all essential causal relations. In terms of cell performance prediction, optional models can be applied for channel pressure drop evaluation, nitrogen cross-diffusion and membrane wetting.
