Fuel cells work in a similar way to #batteries through chemical reactions between anode and cathode, in which #hydrogen and oxygen serve as reactants. Hydrogen is split into electrons and protons, with protons migrating through a membrane to the cathode side, while electrons pass through an external circuit to get to the cathode. đđ§
There they react with oxygen and protons to form water, releasing energy. This process produces about 1.2 volts per cell, similar to a small flashlight battery. Multiple cells can be stacked to produce higher voltages - such a stack is called a "#stack" and can weigh up to 250 kg. âĄđ
The #Manipulator shown here is used in the production of exactly these âstacksâ and supports the worker in various activities:
Assembling the stacks: The two end plates, each weighing up to 15 kg, are picked up, safely positioned and precisely placed using the integrated suction device. đ ïž
Â
Moving the stacks: The 250 kg stack can be lifted, swiveled 90 degrees and put down using the manipulator. đïž
