Title: Design and Optimization of PEM Fuel Cell: Deep Learning from Multi-physics Simulation
Abstract:
Polymer electrolyte membrane (PEM) fuel cell has been regarded as a potential power
source for various applications due to its noteworthy features of high efficiency and zero
emission [1-5]. Its performance and dynamics are controlled by electrochemically coupled
transport processes, including fluid flow, phase change, species transport, energy conservation,
and proton/electron conduction, and are important to its practical applications. Artificial neural
network (ANN), inspired by the biological neural networks that constitute animal brains,
provides logical connection between input and output variables to predict output values
according to given input variables. It has been successfully applied to many power and energy
systems to optimize component materials, dynamic control, and system design [2,4,6]. Genetic
algorithm (GA) is a heuristic selection algorithm inspired by Darwin’s law of natural survival. It
is efficient for optimization problems with advantages including not trapping to local minima, in
which other conventional search methods may fail without proper treatment. In this talk, I will
present several fundamental aspects regarding physical phenomena in PEM fuel cell, including
porous media flow field, maximum power output, and fuel cell design, and discuss recent ANNGA approaches [2,6] for porous media flow field optimization and online control to advance
PEM fuel cell technology and applications.
