Teaching Experience

  1. University of Toledo, Toledo, Ohio, USA (Fall 2013) Project Initiator and Client Advisor

M.I.M.E Senior Design Project: “Fuel Cell Installation”

Faculty Advisers: Dr. Nagi Naganathan and Dr. Matthew Franchetti

Design Team: Brian Hoyt, Michael Manzagol, James McGuire,  and Christopher Roloson

This team determined whether it is economically feasible to install a molten carbon fuel cell (MCFC) to supply electricity and heat to The University of Toledo campus. In order to determine the viability of using the MCFC, an analysis was conducted on the unit’s life cycle cost, which included expenses involving transportation, installation, maintenance, and operation of the fuel cell. The results from the analysis were then compared to the cost of electricity from the local utility company. I initiated this project, worked the idea with the City of Westerville, and convinced them to be willing to donate their $1,000,000 fuel cell pending results from the feasibility study. I also obtained the buy in from the COE Dean and the F&C VP (Chuck Lehnert).
