The Discovery and Usage of Hydrogen
Hydrogen fuel cells were invented by Sir William Robert Grove. However, they were not put to use until the 1960s when General Electric established workable proton-exchange membrane cells used as power supplies in the Apollo and Gemini space missions. Now, many years later, there is concern within the U.S. government over th...

A Description of the Several Ways of Packaging Hydrogen
Hydrogen can be "packaged" in several ways, as a fuel gas in a H2/02 powered engine or the newly devised solid state pellet of hydrogen isotopes that contains about the equivalent of 5000 cubic feet of hydrogen and is broken down and releases gas into the second chamber where it goes to the engine for use. There a...

The Potential Markets for Non-Fossil Fuel Hydrogen
ANALYSIS The Potential Markets For Non-Fossil Fuel Hydrogen · Hydrogen, most of it produced from fossil fuels, is already widely used in the chemicals industry, notably in the manufacture of fertilizers and petrochemicals. It would therefore be possible to substitute NFFH in this market. However, the total that could be...

An Analysis of an Experiment on Using the Enzyme Catalase to Rapidly Catalyze the Decomposition of Hydrogen Peroxide into Oxygen Gas and Water
AP Biology Enzyme LabIntroduction: Hydrogen peroxide is formed as a waste product of metabolism in many living organisms. It is toxic and must be quickly converted into other, less dangerous chemicals. To manage this problem, the enzyme catalase is frequently used to rapidly catalyze the decomposition of hydrogen peroxide...
