从能量密度、技术可行性、安全性和成本等方面考虑了小型燃料电池取代便携式设备中电池的前景。燃料电池似乎最适合于需要比目前便携式设备（>20Wh）更多能量存储的应用。随着宽带移动的计算的引入，能源需求（Wh）可能会增加，而具有轻质燃料供应的燃料电池可以显著增加相同体积中可用的能量。然而，与电池相比，由于能量源和能量转换器是分离的，因此燃料电池系统增加了复杂性，并且对于便携式应用，需要仔细评估相关的安全性和可靠性问题。然而，高能量密度电源的预期商业市场具有足够的吸引力以支持显著的发展并加速小型燃料电池的引入，因为电池技术不太可能能够满足移动的劳动力的不断增长的能量需求。
The prospect of small fuel cells replacing batteries in portable equipment is considered in terms of their prospective energy density, technological feasibility, safety and cost. Fuel cells seem to be best suited to applications where significantly more energy storage is required than at present in portable devices (>20Wh). Energy requirements (Wh) are likely to increase with the introduction of broadband mobile computing, and fuel cells with lightweight fuel supplies could dramatically increase the amount of energy available in the same volume. However, in contrast to batteries, since the energy source and the energy converter are separated, a fuel cell system adds complexity and associated safety and reliability issues will need to be carefully assessed for portable applications. However, the prospective commercial market for high energy density power sources is attractive enough to support significant development and accelerate the introduction of small fuel cells since battery technology is unlikely to be able to meet the growing energy demands of a mobile workforce.
