Passive heat exchanger for cooling of proton exchange membrane fuel cell

One of the most important aspects of polymer electrolyte membrane (PEM) fuel cells design and operation is water management. In this type of fuel cells, conductivity of protons through a polymer membrane strongly depends on membrane’s water content [1]. The membrane therefore must be well hydrated throughout a fuel cell. This may seem not to be a problem as water is produced in the electrochemical reaction on the cathode. Depending on local conditions in the cathode porous structures, i.e. temperature, pressure and composition of cathode gas (mixture of oxygen and nitrogen whose composition is changing as oxygen is being consumed), water can be present either as liquid or as vapor. If the cathode gas in immediate vicinity of the polymer membrane is not saturated with water vapor, the membrane can lose its water, which will affect its protonic conductivity.
