Clues

  • a fuel cell is an ellectrical cell thats supplied with fuel and oxygen and uses energy from the reaction between them to generate what (11)
  • hydrogen combines with oxygen to form what (4, 5, 5)
  • this bond enerhy varies slightly depending on what (3, 8)
  • what enargy does every chemical bond have (4, 6)
  • what is lowered by a catalyst (10, 6)
  • what is the reaction between hydrogen and oxygen (10)
  • what isnt effected by the reactionwhen a catalyst is used (3, 8)
  • what propoty prevents hydrogen from being stored easily (9)
  • you can use known bond enargys to calculate what (7, 6, 6)
