Fuel cells are considered to be a likely alternative to current fuel sources. All fuel cells require electrolytes for conducting current. There are several types of fuel cells and they all have electrolytes that determine how the fuel cell works. Phosphoric acid based fuel cells are typically used in stationary applications, and higher power mobile...

Polymer electrolyte membrane fuel cells (PEM-FCs) are becoming an increasingly important technology in both stationary and mobile applications. Problems impeding the development of fuel cell technology mainly involve electrocatalysts and electrolyte membranes. Commercially available membranes limit the operating temperature range to an approximate...

Currently, there is a surge in interest in fuel cell research, as companies across the globe race to take advantage of the high energy capacity that fuel cells provide in comparison to other portable electrochemical systems. Many approaches to fuel cell technology use strong acid electrolytes. Such systems suffer from corrosion problems, which limit...
