The environmental impact is one to two orders of magnitude lower than in conventional systems because of their very low level of pollutant emissions.

The prediction of fuel cell performance is one of the most challenging problems in fuel cell research. Cell Cell Cell Typically, a fuel cell consists a cathode,anode, Cell width and 1 cm 3 cm 5 cm electrolyte and bipolar plates as shown in Figures 1.

This document reviews the design and fabrication process of electrodes in Costa Rica, to be use in electric cell-substrate stimulations and electrochemical impedance sensing up to 10 kHz. The effect … Expand. The subsystem contain four Figure 4 Photocell current module in the system blocks, the input is the operating temperature in degree centigrade and the two outputs is the temperature T in Kelvin and the reference temperature Tref in Kelvin's too.

The subsystem job is to convert the temperature units, the reference temperature assumed to be 25 Co which is room temperature, figure 3 shows details of the temperature subsystem. The inputs are diode reverse saturation current A , the temperature T in Kelvin and the reference temperature Tref in Kelvin's too. The parameters used in this block are electron charge, Boltzman'n constant, band gap for Silicon and diode ideality factor.

The details of this block shown in figure 9, which is the subsystem of the block. Figure 5 Photocell current subsystem module 3.

The inputs are short circuit current A and operating temperature Kelvin and the output is the diode reverse saturation current A , the parameters used in this block is electron charge, voltage across the output terminal, number of series cells, Boltzman'n constant and diode ideality factor.

The details of this block shown in figure 7, which is the subsystem of the block. Figure 8 Shunt resistance current module in the system Figure 6 Diode reverse saturation current module in the system Figure 9 Shunt resistance current subsystem module 3. The inputs are temperature T in Kelvin, short circuit current A , Photocell current A and voltage across the output terminals volt while the outputs are photovoltaic current and voltage.

The parameters used in this block are electron charge, Boltzman'n constant, diode ideality factor, number of series and parallel cells and value of series and shunt resistance.

The details of this block shown in figure 10, which is the subsystem of the block. Figure 13 I-V Assorted curves for various Temperature and constant Irradiance The effect of increasing irradiance while temperature was fixed 30o is increasing the output and short circuit current, the output voltage almost not affected very much. The third and fourth tests show the P-V curves for different irradiance and operating temperature as shown in figure 14 and 15, increasing the irradiance cause Figure 11 Solar cell system modeling simulation increasing the max power and max peak current, on the other hand increasing temperature cause to reduce the max power and max peak voltage [15].

In addition, in this simulation, changing the parameters of table 1 can be done very easily by changing the constants block. These results obtained by using output scope block and to workspace block in Matlab-Simulink. Figure 12 and 13 shows the I-V curves for different irradiance and different temperature respectively.
