1. A hydrogen fuel cell is more efficient than a combustion reaction because very little of the released energy is released as HEAT.

We need more energy emit as light and less heat. Lesser the heat more the efficiency.

2. when used at home a fuel-cell illuminates the need for an electrical grid because the cell is portable.

As said, it is portable.
