Introduction

Green technologies are ever so popular nowadays. Fuel cell technology holds the promise of high-efficiency utilization of fossil and alternative fuels. The purpose of the project is to provide a capstone experience to students in the Fuel Cell course. It ties together the complexity of the chemistry and electro-chemistry processes encountered in fuel cells. While PEM fuel cells are destined for vehicles and other mobile applications, Molten-Carbonate Fuel Cell (the backbone of the project) is being developed by Fuel Cell Energy (fce.com) for stationary applications. The simulations are run with various alternative fuels like digester, landfill and pyrolysis gas. Students are required to complete significant research of alternative fuels, utilize modern modeling tool, and read scientific and popular-scientific literature.

Assignment

The final team report (one per team) will consist of two sections:
MCFC Operation Summary-50%
Simulation Results-50%

Topics to address in the Summary:

1.    Fuel reforming in MCFC
2.    Operating conditions inside of the cell and main chemical reactions
3.    Operational diagram (draw your own)
4.    Variety of MCFC types produced by Fuel Cell Energy
5.    Other manufacturers (1-2) and their product
6.    Describe the details of Sierra-Nevada brewery installation
7.    CA economic stimulus to MCFC installations

Simulation results:

1.    Simulate all of the gases given in the paper, carefully review all of the steps
2.    Compare Nernst voltages produced
3.    Provide your inputs and results
4.    Find a gas composition of a landfill gas, water treatment (digester gas) and biomass pyrolysis
5.    Feed those in the program—compare results to the initial set of gasses
6.    Write conclusions section for your simulations.
