Fuel cells are much more efficient in converting fuel into energy than internal combustion engines. The most efficient type of fuel cell is the Alkaline Fuel Cell (AFC).
Fuel cells convert fuel into electricity. The amount of energy stored depends on the quantity of fuel. Hydrogen-oxygen fuel cells, such as the low temperature alkaline fuel cell, have zero carbon footprint, are totally non-polluting and in addition to electricity, they produce pure water.
Alkaline fuel cells (AFC) were used to power the Apollo Moon Mission in the 1960s, in which liquid hydrogen and liquid oxygen were converted to electricity and drinking water. The catalyst used was the precious metal platinum, until recently virtually the only choice to fulfill the power requirements of low temperature fuel cells
In collaboration with Prof. Karl Kordesch, Apollo Energy Systems continued the development of the circulating electrolyte AFC at the University of Graz, Austria, and introduced the concept of hydrogen storage in the form of compressed liquid ammonia. We developed and patented the ammonia cracker to feed hydrogen directly into the AFC.
Phase 2 of this program is now underway. Apollo has had success with taking out all of the precious metals from the fuel cell electrodes, thereby giving our Apollo AFC the potential to be the lowest cost of all fuel cells on the market.
Fuel cells operate most efficiently at a constant power output. Therefore the AFC is coupled with a battery to provide peak power – the battery is then recharged by the fuel cell during periods of low power demand.
The Apollo Power Plant consists of the fuel cell stack, balance of plant, tripolar lead-cobalt battery, inverter and associated electrical systems.
