Single-Use Batteries. A common primary battery is the dry cell, which uses a zinc can as both container and anode ("–" terminal) and a graphite rod as the cathode ("+" terminal).The Zn can is filled with an electrolyte paste containing manganese(IV) oxide, zinc(II) chloride, ammonium chloride, and water.

A somewhat oversimplified diagram of a fuel cell in which the cell reaction is the production of water from hydrogen and oxygen is shown in Figure (PageIndex{1}). Figure (PageIndex{1}): A hydrogen-oxygen fuel cell. Hydrogen enters the cell through a porous carbon electrode which also contains a platinum catalyst. Oxygen is supplied to a
Let''s take a look at this simple diagram. The molecular formula for water is H2O. This means that it is made from hydrogen and oxygen. When electrical current passes through water, this generates both hydrogen and oxygen gas. This is called "electrolysis" of water. Fuel cells use this electrolysis process in reverse – in other words

There are two main ways of producing hydrogen with coal as raw material—coal coking and coal gasification. Coal coking refers to the process whereby coal is heated to 900–1,000 °C in the absence of air to produce coke, with coke oven gas as the by-product. Generally, 300–350 Nm 3 of coke oven gas can be produced from every ton of coal. The
This lab exercise exposes students to a potentially new alternative energy source—hydrogen gas. Student teams are given a hydrogen generator and an oxygen generator. They balance the chemical equation for the combustion of hydrogen gas in the presence of oxygen. Then they analyze what the equation really means. Two hypotheses are given, based

Hydrogen is emerging as a new energy vector outside of its traditional role and gaining more recognition internationally as a viable fuel route.
Hydrogen is passed through the anode and oxygen is passed through cathode. At the anode, hydrogen molecule gets split into electrons and protons. The protons pass through electrolyte
Hydrogen is not readily available in its pure form, though, so it can be obtained through the chemical process of electrolysis. Electrolysis uses electrical energy to split water molecules into hydrogen and oxygen. The hydrogen is then stored

Applied Chemistry 2 Explain Hydrogen Oxygen Fuel Cell with a neat diagram. Definition of Fuel Cell: A fuel cell is a device that produces electricity through a chemical reaction between a source fuel and an oxidant. In a fuel cell, the catalyst facilitates the reaction of oxygen and hydrogen.
Working Principle: The working principle of a hydrogen fuel cell is based on the conversion of hydrogen and oxygen into water, along with the production of electricity. Initially, hydrogen gas is supplied to the anode, where it is split into positively charged hydrogen ions (protons) and negatively charged electrons.
