Automotive Fuel Cell Systems: Testing Highly Dynamic Scenarios

Development of Sensors for Automotive Fuel Cell Systems

The team assembled for this project will perform the following tasks: 1. Obtain representative samples of physical parameter sensors currently available to meet the targets specified in the fuel cells section of the Hydrogen, Fuel Cells and Infrastructure Technologies Program (HFCIT) Multi-Year R,D&D Plan (MYP). 2. Design and construct a facility for testing physical and chemical sensors under ...

Control-Oriented Modeling and Analysis for Automotive Fuel Cell Systems

Fuel Cells are electrochemical devices that convert the chemical energy of a gaseous fuel directly into electricity. They are widely regarded as a potential future stationary and mobile power source. The response of a fuel cell system depends on the air and hydrogen feed, flow and pressure regulation, and heat and water management. In this paper, we develop a dynamic model suitable for the cont...

On the Control of Automotive Traction PEM Fuel Cell Systems

Dynamic Simulation of Fuel Cell Systems

The development of dynamic simulation tools for fuel cell systems and fuel cell/gas turbine (FC/GT) systems is required to understand the response of fuel cell systems to both scheduled and unscheduled perturbations. These tools supply the foundation on which control strategies can be developed and tested before they are actually implemented in a physical system. For high temperature fuel cell ...

Dynamic investigation of hydrocarbon proton exchange membrane Fuel Cell

Sulfonated polyether ether ketone (SPEEK) is categorized in a nonfluorinated aromatic hydrocarbon proton exchange membrane (PEM) group and considered as a suitable substitute for common per-fluorinated membranes, such as Nafion, due to wider operating temperature, less feed gas crossover, and lower cost. Since modeling results in a better understanding of a phenomenon, in this study a dynamic o...
