Unmanned aerial vehicles (UAVs) are used for many purposes; however longer flight time and quiet operation are always desired. To achieve these two goals a light-weight open-cathode fuel cell is being developed. Longer flight times require either more fuel or a higher energy density fuel and the means to use it efficiently. Hydrogen fits this condition as its energy density is higher than typical fuels like gasoline or propane and much higher than any battery types. Also, fuel cells tested in the lab have obtained efficiencies greater than 90%; but, the weight of a conventional fuel cell is an issue with regard to the UAVs. The fuel cell presented in this study attempts to tackle the weight issue. To decrease weight, metallic bipolar plates were used in place of the typical carbon composite plates. Metallic bipolar plates have the added benefit of reducing material and machining cost. The open-cathode design allows oxygen to be supplied and the stack cooled from the same stream of air. This reduces the balance of plant for fuel cell operation and so, reduces cost and most importantly, weight. The fuel cell presented in this study will allow for longer flight times and quiet operation when compared to the conventional power sources.
