In its new strategic plan, the engineering firm of BS Engineering has identified the fuel cell industry to be a future market for its services. To position the firm in this marketplace, it has decided to invest internally in the development of an analysis tool that can be used in the design of fuel cell systems. As associates of the firm, the student team assignment is to develop Matlab $($or Mathematica or Python$)$ code for two different fueled fuel cells that will perform performance calculations. The team is then to demonstrate the Matlab $($or Python, etc$)$ code through the development of performance characteristics for the fuel cells. Please form your teams by Wednesday.

Your software should be developed for the following fuels: hydrogen and one of assigned methanol, ethanol, or natural gas $($and more$).$ Each team must thus develop a hydrogen fuel cell code and then either a methanol or ethanol or natural gas fuel cell code. The input parameters for the code are:

Fuel cell temperature

Required power for the fuel cell system

Required voltage for the fuel cell system

Outputs should include:

Fuel cell current

Fuel cell voltage

Fuel cell efficiency

Number of fuel cell stacks required

Fuel consumption rate

To demonstrate the code the team should provide the following graphs for a $10kW$ fuel cell system with a required voltage of $12$ volts for each fuel over a temperature range of $15C$ to $250C.$ Note that not all fuels can operate in this entire temperature range $($ you will get negative efficiencies$).$

Graph $1$: Fuel cell efficiency versus fuel cell temperature

Graph $2$: Fuel cell voltage versus fuel cell temperature

Graph $3$: Fuel consumption rate versus fuel cell temperature

The team is required to submit a technical memo that documents their work $($model used and one example solved$),$ including the six graphs required. Software codes are to be included as an appendix to the report. In your discussion, present the advantages$/$disadvantages of each fuel considered and what type of fuel cell you would recommend for a given fuel. You should also work out on problem per fuel for one temperature to ensure that your code generates correct results.
