Source sentences:
text: Since the efficiency of a fuel cell is directly proportional to the power generated, its efficiency is almost proportional to its voltage.
text: Since the efficiency of a fuel cell is directly proportional to the power generated, its efficiency is almost proportional to its voltage.
text: The net effect of this is that the efficiency also drops as the power drawn from the cell increases so that the efficiency is almost proportional to the output voltage.
