Hydrogen is the most basic element in the universe, consisting of only one proton and one electron. Its chemical symbol is H. When combined with oxygen, it produces water. Hydrazine (N2H4) is commonly used as a liquid rocket fuel. Allis-Chalmers developed a fuel cell in 1964 using hydrazine-oxygen for a one-man submarine tested by the Electric Boat Company. According to NASA, hydrazine is costly, corrosive and hazardous. NASA currently uses hydrazine in the Auxiliary Power Unit (APU) of the space shuttle. However, due to its toxicity, it is scheduled to be replaced by a better battery system. Other fuel cells on the space shuttle use pure hydrogen. • There are many news ...  more
