Fuel Cell Plates

Bipolar plates constitute one of the most important parts of a PEM fuel cell stack with multifunctional character. It distributes fuel gas and oxygen over the whole active surface area, joins together the anode of one cell to the cathode of another, pro–vides electrical conduction between cells, facilitates fluid management within the cells, removes heat from the active areas, among others.
