One of the oldest designs 70% efficient Used in Space Catalyst is a non-precious metal Operates at 75-150°F
30
The most developed 40% efficient Platinum catalyst Operates at 400°F Unsuitable for cars
31
Best suited to power towns 50-60% efficient Catalyst is a non-precious metal Operates at 1830°F Produces steam
32
Best suited for cars and buses 60% efficient Catalyst is a non-precious metal Operates at 1120°F Capable of internal reforming
33
CH 3 OH and steam supplied No need for a reformer Methanol is a liquid Operates at 180°F 3-4 years behind the others
34
Operate at low temperatures Have a platinum catalyst Can handle changing power demands Good candidate for automobiles Starts quickly
