It is difficult to determine a clear winner between Saitama from "One Punch Man" and Zeno from "Dragon Ball Super" as they are characters from different universes with vastly different powers. Saitama is known for his unmatched strength and ability to defeat any opponent with a single punch, while Zeno is one of the most powerful beings in the Dragon Ball universe, capable of erasing entire universes with a mere thought. Ultimately, the outcome of a battle between them would depend on the specific circumstances and rules set by the creators of each series. **

A hydrogen fuel cell produces energy through an electrochemical reaction between hydrogen and oxygen. Hydrogen gas is fed into the anode side of the fuel cell, where it is split into protons and electrons. The protons travel through an electrolyte membrane to the cathode side, while the electrons flow through an external circuit, creating an electric current. At the cathode, the protons, electrons, and oxygen from the air combine to produce water and release energy in the form of electricity. **

It is difficult to determine who would win in a battle between Saitama from "One Punch Man" and Zeno from "Dragon Ball Super" as they are both incredibly powerful characters in their respective universes. Saitama is known for his unmatched strength and ability to defeat any opponent with just one punch, while Zeno is the all-powerful ruler of the multiverse in the "Dragon Ball" series. Ultimately, the outcome of a battle between them would depend on the context and rules set by the creators of the crossover. **

It is subjective to determine if Zeno is the strongest anime character as strength can be measured in various ways such as physical power, intelligence, abilities, or influence. Zeno, from the anime Dragon Ball Super, is incredibly powerful as he possesses the ability to erase entire universes with a single thought. However, there are many other anime characters with different unique abilities and strengths that could rival or surpass Zeno in different aspects.

The universes do not rebel against King Zeno because he holds immense power and control over them. As the ruler of the universes, King Zeno likely has the ability to suppress any potential rebellion through force or manipulation. Additionally, the universes may fear the consequences of going against King Zeno, such as retaliation or destruction. Ultimately, the universes may feel powerless to challenge King Zeno's authority and choose to comply in order to avoid conflict. **

A hydrogen fuel cell is a device that converts the chemical energy of hydrogen and oxygen into electricity through an electrochemical reaction. It consists of an anode, a cathode, and an electrolyte membrane. Hydrogen gas is fed into the anode, where it is split into protons and electrons. The protons pass through the electrolyte membrane to the cathode, while the electrons flow through an external circuit, creating an electric current. At the cathode, the protons, electrons, and oxygen from the air combine to produce water and heat as byproducts. This process is clean and efficient, making hydrogen fuel cells a promising alternative to traditional combustion engines. **

The universes do not rebel against King Zeno because he holds immense power and authority over them. As the ruler of the universes, King Zeno is likely to have loyal followers and supporters who uphold his rule. Additionally, the universes may fear the consequences of rebelling against King Zeno, such as facing his wrath or being destroyed. Ultimately, the universes may choose to submit to King Zeno's rule in order to maintain order and stability within their realms. **
