WebWhen hydrogen combines with oxygen to produce water in a fuel cell the hydrogen is taken from a tank carried in the vehicle and the oxygen is taken from the air (as it is in gasoline-combustion vehicles). The reaction is. 2 H 2 + O 2-> 2 H 2 O . So, for every 2 hydrogen atoms taken from the fuel tank, 1 oxygen atom is taken from the air. Web15 aug. 2024 · A hydrogen fuel cell enables hydrogen to be combined electrochemically with oxygen to produce electricity, water, and heat. One fuel cell alone only produces a small amount of power. However, grouping the individual fuel cells together creates a fuel cell stack (as shown below in the diagram).
