Effect of startup modes on cold start performance of PEM fuel cells with different cathode flow fields
Wenzhe Zhang, Xingxiao Tao, Qifeng Li +4
Proton Exchange Membrane Fuel Cell (PEMFC) is widely recognized for its cleanliness and high efficiency, but is still facing challenges in cold environments. At low temperatures, t…
PROMETHEE-based Modeling of Endogenous Behavioral Uncertainty of EV Owners
Dipayan Sarkar, Qifeng Li
The electric vehicle (EV) charging demands (CD) are jointly determined by the EV owners' behavior (i.e., human factor) and the electricity prices (i.e., decisions of distribution s…
A Data-embedded Solution Paradigm for Nonconvex Probable Event Constrained Optimization
Qifeng Li
This paper introduces a new modeling framework for optimization under uncertainty, called Probable Event Constrained Optimization (PECO). Unlike conventional chance-constrained for…
Effects of gas diffusion layer thickness on PEM fuel cells with composite foam-rib flow fields
Wei Gao, Qifeng Li, Kai Sun +3
Gas diffusion layers (GDLs) play a crucial role for the performance of proton exchange membrane fuel cells (PEMFCs). The utilization of composite foam-rib flow fields (CFRFFs) can…
Mass transfer and water management in proton exchange membrane fuel cells with a composite foam-rib flow field
Wei Gao, Qifeng Li, Kai Sun +3
Mass transfer capability of reactants and hydrothermal management is important for the performance and durability of proton exchange membrane fuel cells. In the conventional rib fl…
Probable Event Constrained Optimization and A Data-embedded Solution Paradigm
Qifeng Li
This paper solves a new class of optimization problems under uncertainty, called Probable Event Constrained Optimization (PECO), which optimizes an objective function of decision v…
