Fuel cells for mobile devices

The preparation of self-humidifying Nafion/various Pt-containing SiO2 composite membranes and their application in PEMFC

“…Proton exchange membrane fuel cells (PEMFCs) have been concerned as one of alternative power sources for portable and stationary applications due to several advantages such as their low emission, high energy conversion efficiency, simplicity of operation and high power density [1][2][3]. Despite many advantages, however, it has some barriers such as durability, cost and flexibility of operation toward the commercialization.…”

Improvement of water management in air-breathing and air-blowing PEMFC at low temperature using hydrophilic silica nano-particles

“…Especially a small scale fuel cell is considered an alternative power source to replace batteries for many portable electronic devices, such as laptop computers, cellular phones and personal digital assistants (PDAs) [1][2][3]. However, conventional PEMFCs have some limitations for portable applications, because there are many power consuming auxiliary devices such as pumps, valves, fans, humidifiers, etc.…”
