With a fuel cell, chemicals constantly flow into the cell so it never goes dead -- as long as there is a flow of chemicals into the cell, the electricity flows out of the cell. Most fuel cells in use today use hydrogen and oxygen as the chemicals.
CFC'S or Chlorofluorocarbons are molecules which demolish the ozone layer. The ozone layer is made up of O3 or ozone molecules these reflect UV rays (harmful ultra violet ligh â¦ t) the CFC'S smash up the O3 into O2 molecules (the type we breathe) these do not reflect UV so we suffer.UV is radiation and increases the chances of skin cancer.he ozone layer is made up of O3 or ozone molecules these reflect UV rays (harmful ultra violet ligh â¦ t) the CFC'S smash up the O3 into O2 molecules (the type we breathe) these do not reflect UV so we suffer.

There are several gases that are classed as greenhouse gases.    They are:   water vapor  carbon dioxide  ozone  methane  nitrous oxide  CFCs     Energy â¦ from the sun heats the earth's surface and atmosphere, which  drives the earth's weather and climate.es. Chlorofluorocarbons are greenhouse gases. They were largely responsible for damaging the ozone layer, but they have been checked since the Montreal Protocol (1987 - 1999), which has been ratified by 196 countries.
