Residential systems fuel types

Most analysts tend to classify the types of applications in a small number of pockets portable, which covers personal electronics and units that have been designed to be moved around UPS systems residential fuel cells power plant fuel cells light-duty FCV fuel cell buses and niche transport, which covers everything that is not a LDV or bus and APUs. 

Of all the system characteristics of DMFC with regard to commercialization as a mobile device energy source, energy efficiency, energy density, power density, and cost have to be competitive with rechargeable batteries. These requirements are somewhat different from other types of fuel cells for residential or vehicle application, which can utilize auxiliary compartments more freely. These compartments include a balance of plant (BOP), such as a compressor or pump, for fuel and oxidant supply, humidifier, heat exchanger, and so on. These comparnnents have to be miniaturized effectively or eliminated. This means that the materials in the stack should themselves have the functions of BOP.
