Water Removal and Management

Water removal by moving gas stream from the cathode electrode surface. 

Fuel cells require a cooling system to maintain the operation of the cell at essentially a constant temperature to sustain the desired operating condition and avoid condensation and dryout in the fuel cell. Additionally, the system 

High-performance cooling mechanisms such as forced convection liquid cooling and two-phase flow boiling heat transfer have good potential for use in PCs. Some of the key criteria for the selection of the cooling fluid are as follows the fluid must be non-corrosive, nonfreezing, environmentally safe, and an electrical nonconductor, that is, dielectric to avoid any short circuits. 

The cooling system will be used to remove the heat generated during the operation of the fuel cell to maintain the near-isothermal operating conditions. The heating system will be used for heating the fuel cell during 

Start-Up under cold environment conditions using the same integrated flow channel flow loop.

In a fuel cell power system, the stack is integrated with a number of subsystems such as air supply system, fuel supply system, water removal and management cooling and heat management system and power supply management and control subsystem as shown in Figure 10.7.
