cells and fuel cells. Flashcards
what do chemicals in cells react together to release?
energy.
how can a simple cell be made?
placing 2 different metals into a beaker containing an electrolyte.
what is the voltage of a cell dependant on?
type of electrode and electrolyte used.
if cells are joined in series what can happen?
produce a higher voltage.
what are fuel cells a very efficient way of producing what?
electrical energy.
what do most fuel cells use?
hydrogen.
in a hydrogen fuel cell what is supplied to it?
hydrogen and oxygen.
in a hydrogen fuel cell what happens after the fuel is oxidised?
produce a potential difference ( voltage.)
overall what is the hydrogen in a fuel cell oxidised to form?
water.
what are the advantages of fuel cells?
produce water- non polluting.
lightweight and small.
no moving parts so unlikely to break down.
