A hydrogen battery functions by storing excess electricity produced from a solar panel array as hydrogen in a set of canisters full of hydride. The hydrogen is then released to act as a battery and power various devices.
However, while the energy in batteries is stored via a chemical reaction, the energy in hydrogen cells is stored in hydrogen gas. Hydrogen gas is stored in a tank which feeds fuel cells, each made up of negative and positive terminals (anodes and cathodes) separated by an electrolyte.
Hydrogen, Batteries and Fuel Cells provides the science necessary to understand these important areas, considering theory and practice, practical problem-solving, descriptions of bottlenecks, and future energy system applications.
Fuel cells derive their power from hydrogen stored on the vehicle, and batteries obtain their energy from the electrical grid. Both hydrogen and electricity can be made from low or zero carbon sources including renewable energy and nuclear energy.
This can be achieved by either traditional internal combustion engines, or by devices called fuel cells. In a fuel cell, hydrogen energy is converted directly into electricity with high efficiency and low power losses. Hydrogen, therefore, is an energy carrier, which is used to move, store, and deliver energy produced from other sources.
The title covers hydrogen as an energy carrier, including its production and storage; the application and analysis of electrochemical devices, such as batteries, fuel cells and electrolyzers; and the modeling and thermal management of momentum, heat, mass and charge transport phenomena.
