Project Description

Type of Project:	Model
Category:	Vehicle Options
Objectives:	Develop a dynamic system model of a solid oxide fuel cell based auxiliary power unit and design a system controller to minimize diesel fuel consumption, maximize operating lifetime and satisfy electrical load requirements for Class VIII truck applications; Develop analytical models and perform testing to determine the dynamic structural response and vibrational limits of SOFC-based APU systems in a Class VIII truck operational environment.
