Fuel cell engineering: water management

Hydrogen fuel cells offer a clean and sustainable way to produce electric energy by combining hydrogen and oxygen, with the only byproduct being water. They can be used in a wide range of applications, from powering vehicles to providing backup power for remote locations.

For PEM fuel cells, a good balance of water in the bipolar plate and the cathode is critical for an efficient operation. Too much water can lead to a decrease of electric output, while not enough water can lead to reduced durability. This presentation addresses the main aspects of water management in a fuel cell with a focus on the gas diffusion layer and micro-channels of the bipolar plate. A workflow centered on multiscale multiphase fluid simulations is demonstrated.

Integrated 1D and 3D Workflow for EV Battery System Development 

With the growing market for electric vehicles comes a need for quick and accurate simulation of the thermal behavior of electric vehicle battery systems. This battery system development with a focus on thermal performance can be done using full 3D computational fluid dynamics simulations with conjugate heat transfer applied to the 3D battery module and cold plate geometries. However, for early conceptual design, where many design iterations need to be tested, this can become prohibitively expensive. There is also a need for quick and accurate battery modeling when integrated into larger 1D systems of the vehicle. This talk, therefore, discusses the correlation of the thermal behavior of 3D battery model systems with numerically cheaper 1D battery models developed using the Dymola Modelica library. Examples of the good correlation achieved between the 3D and 1D models are presented through a canonical liquid-cooled battery pack with uniform loading and, subsequently, the battery pack with a load cycle based on the EPA Urban Dynamometer Driving Schedule.
