| How a fuel cell works.|
Standard fuel cells use electronics to control power, requiring complex systems to manage humidity, fuel recovery, and recycling in order to maintain acceptable efficiencies. Because fuel cells do not operate with a thermal cycle, they can have high efficiencies, especially when operated at low power densities. As a general rule, the more current drawn, the lower the efficiency. For example, a cell running at 0.6 V has an efficiency of about 50%, while the remaining 50% is converted into heat.
The new process feeds in hydrogen to match the required power output and functions as a closed system that uses waste water to regulate the size of the reaction chamber. The design uses 100% of the fuel and eliminates the need for a recycling system.
The next step is to connect several fuel cells together to increase power, and compete with internal-combustion engines in cars and trucks.
