PEMFCs vs BEVs Flashcards
Name five pros of PEMFCs for cars over BEVs.
Flexibility on tank location, better packaging.
Can swap empty tanks with full ones to “charge” rapidly.
Hydrogen is most abundant material on earth, so no risk of shortages like there are for cobalt.
Cobalt also has questionable ethics in attaining it.
Lifetime of FC is longer than battery.
Name four cons of PEMFCs for cars over BEVs.
Not many hydrogen refill points, whereas can charge BEV in many places.
Storing hydrogen in compressed gas form is dangerous since it is highly flammable.
Specific FC coolant required to avoid de-ionisation and oil-less turbos are required to avoid contaminating MEA, so they’re expensive.
Not all hydrogen is naturally available so the overall energy efficiency of FCs can be lower than that of BEVs.
