B2) Considering the following Polarization and Power curve sets shown below, select and verify any two corresponding points on two coressponding Polarization and Power curves. Use the trapezoidal rule to evaluate the power value expressed by the area under the polarization curve for two selected points on the power curve. 1.200.00 1.000.00 Voltage (V) #:00E-01 6.00E-01 4.00E-01 2006-01 0.00E+00 0.00E+00 Effects of temperature at low pressure and low relative humidity +-62 C, 5 psl, 25% RH -62 C, 5 psi, 25% RH →74 C, 5 psl. 25% RH +-74 C, 5 psl, 25% RH Voltage: Power Density: 2:00E+02 -50 C, 5 psl, 25% RH 50 C, 5 psl, 25% RH 4.00E+02 1 Pow. 1 Pol. 6.00E+02 8.00E+02 1.00E+03 Current Density (mA/cm²) 1.20E+03 3 Pow. 2 Pow. 3 Pol. 2 Pol. 1.40E+03 4.50E-01 4.00E-01 3.506-01 3.00E-01 2.506-01 2006-01 1.50€-01 1.00E-01 5.00€-02 0.00E+00 1.60E+03 Power density (mW/cm²) Polarization and power density curves for different cell temperatures at low fixed operating parameters of 5 psi and 25% RH B2) Considering the following Polarization and Power curve sets shown below, select and verify any two corresponding points on two coressponding Polarization and Power curves.
