2 Simulation Results and Discussion
Simulation of PEM fuel hp laptop battery cells are an effective area of 5cm2 of the monomer, DC market. Finite volume method to solve the model equations and their boundary conditions. Table 1 are the model of the PEM fuel cell involves the basic parameters.
Figure 2 are in the cathode and anode humidification temperature of 333 K, current density of 1.08A/cm2, the cathode hp omnibook xe3 battery, hp hstnn-db02 catalyst layer of oxygen distribution. As can be seen along the direction of air flow, oxygen volume fraction on the decline, mainly because of oxygen consumed in the cathode due. In the vertical, the catalyst layer from the gas diffusion layer interface to the proton exchange membrane interface, the oxygen volume fraction lower. This is like that in the cathode catalyst layer of oxygen concentration are uneven, the hp hstnn-ub02, hp dp390a electrochemical reaction rate is also uneven.
Figure 3 is a humidification temperature of 333 K, average current density of cathode catalyst layer 1.08A/cm2 when the hp pp2100, compaq presario r3000 battery current density distribution. As can be seen from the graph: the direction along the gas channel, the current density gradually reduced. Catalyst layer near the spread from near the proton exchange membrane, current density increased. This is because in this direction, the proton mass fraction increased electrochemical reaction caused by speed. This also indicates when the battery temperature of 353 K, humidification temperature of 333 K, the proton transfer is the cathode in the process of mass transfer hp pavilion zv5000 battery, hp pavilion zv6000 battery control process.
