The need for energy is growing day by day, fuel cells are a good source of green energy. One of the greatest challenges associated with PEMFCs is the water and thermal management.
The water balance in the fuel cell stack is one of the greatest
challenges associated with PEMFCs. In each cell, as the chemical reaction takes place, water
is generated. There is a tendency for the fuel cells to both flood and dry-out
depending on the load and the operating conditions. The water content of the
polymer membrane affects the proton conductivity and activation overpotentials. When temperature
increases, electrochemical activities rise and the reaction happens at a
maximum rate, which thus raises efficiency. At the same time membrane dry-out
occurs at elevated temperature, resulting in decreased conductivity of protons.- Introduction to Fuel Cell
