How is hydrogen used to generate electricity in a pem fuel cell?
hydrogen combusts with oxygen to produce heat, which is used to turn a turbine that produces electricity.
hydrogen atoms are separated into protons and electrons, and the movements of these particles generate electricity.
hydrogen combusts with oxygen to produce water, and the flow of the water is used to turn a turbine and produce electricity.
hydrogen atoms are separated into protons and electrons, which combine with oxygen to produce water that is then heated in a solar collector to produce electricity.

Hydrogen atoms are separated into protons and electrons, and the movements of these particles generate electricity.

Explanation:

The hydrogen cell is an electrochemical cell. It involves the electrochemical reactions involving oxygen and hydrogen.

A fuel cell is a device that converts chemical the energy stored in molecular bonds into electrical energy. A typical PEM (Proton Exchange Membrane) cell uses hydrogen gas (H2) and oxygen gas (O2) as the required fuel. The final reaction products in the cell are water, electricity, and heat.

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
