Puro® Stacks

Powering the future with hydrogen fuel

For fuel cells, a single cell composed of a group of electrodes and electrolyte plates has a relatively low voltage and high current density.

To obtain high voltage and power, multiple individual cells are typically connected in series to form a fuel cell stack. Adjacent individual cells are separated by metal plates, which are used to connect the front and rear cells and provide gas flow paths for each cell.

Individual Fuel Cells

Each fuel cell within the stack consists of an anode and a cathode, separated by an electrolyte. The anode is the electrode where hydrogen is supplied, and the cathode is the electrode where oxygen is provided. The electrolyte allows the movement of ions between the anode and cathode while preventing the direct mixing of hydrogen and oxygen gases.
