Problems with fuel cell module in comsol 5.6

Question1 In comsol 5.6, only the fuel cell module is used, in which the reaction gas is set to pure hydrogen and oxygen (excluding water). The final reaction result does not have the mole fraction of water, but isn't this reaction producing water? Why will there be no water in the end? Question2 In comsol 5.6, the fuel cell module and the solid heat transfer module are used to simulate the battery temperature change caused by the heat produced by the fuel cell (the boundary of the battery is set as thermal insulation). The overall results show that the heat source after the fuel cell is working is mainly generated in the cathode catalytic layer, but the temperature of the cathode catalytic layer in the overall battery temperature is not very high, even lower than the anode catalytic layer. I don't quite understand this.
Looking forward to your answer, thank you!
