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. 🔋💧
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. ⚡🔌
The #Manipulator shown here is used in the production of exactly these “stacks” 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. 🛠️
Moving the stacks: The 250 kg stack can be lifted, swiveled 90 degrees and put down using the manipulator. 🏗️
