FuelCell Energy's (NASDAQ:FCEL) fuel cell technology could be a major step forward in how we produce electricity and potentially transportation fuels. If only the company could gain some momentum in becoming profitable. While sales have been growing steadily over the past five years, the company has hit a couple bumps so far in 2014. Surprisingly, though, sales is not the biggest issue for FuelCell Energy, which is actually selling its products and services for a profit. This past quarter saw gross profit slip to a mere 4.1%, which is less than a fifth of its most direct competitor, Ballard Power Systems (NASDAQ:BLDP).

Tune into the video below to find out how much of an effect these weak margins will have on the path to profitability of both FuelCell Energy and Ballard Power Systems.
