Problem 1: Fuel cell A fuel cell is an electrochemical system that uses reactants to produce electricity. A polymer electrolyte membrane (PEM) fuel cell is a popular technology that uses a chemical reaction involving hydrogen and oxygen to produce electricity and water as by-products. A hydrogen fuel cell design which operates at 1 (atm) pressure has the polarization curves given below. Knowing that the membrane area is 100[cm]; a) Find the minimum current density, maximum current density, minimum cell voltage and maximum cell voltage for the typical operation range for the fuel cell and use fprintf to display the results. Try degree polynomials of 2 through 4 to determine which degree polynomial will give the smallest error MSE. Use MATLAB's function polyfit, which returns the coefficients for each of the three polynomials. Then use MATLAB's function polyval to create for each polynomial: a) A table containing J, V_C, and V where VC is the approximating curve for HVs.Q. (b) A plot of VCVs.J (solid line) and V vs. J (small circles, all plots on the same page)
