A stack of solid polymer fuel cells is an assembly of single fuel cells connected in series, located between end plates, fixed with tie rods, providing rigidity and planarity of the structure. Fittings and solenoid valves are installed in the end plates to control the operation of the fuel supply system. The stack also includes a casing with oxidant supply and thermal control systems installed in it. The transmission of the generated electricity is carried out using electrical outlets. Hydrogen is used as a fuel, air is used as an oxidizing agent.
