PEM fuel cells use a proton conductive polymer membrane as electrolyte. PEM stands for Polymer Electrolyte Membrane or Proton Exchange Membrane. Sometimes they are also called polymer membrane fuel cells, or just membrane fuel cells. This technology has drawn the most attention because of its simplicity, viability, quick start-up, and it has been ...

Dynamic Characteristics of PEM Fuel Cells
IEEE 36th Conference on Power Electronics Specialists, 2005., 2006Fuel cell applications have become increasingly attractive. Therefore, comprehensive models, simulation and analysis tools are required to characterize fuel cell behavior. For years, the focus has been on describing the steady state characteristics of fuel cells, which is an important application but certainly not the only one.

A fuel cell is an electrochemical device that continuously and directly converts the chemical energy of externally supplied fuel and oxidant to electrical energy. Fuel cells are customarily classified according to the electrolyte employed. The five most common technologies are polymer electrolyte membrane fuel cells (PEM fuel cells or PEMFCs), alkaline

High temperature PEM fuel cells
Journal of Power Sources, 2006Abstract There are several compelling technological and commercial reasons for operating H 2 /air PEM fuel cells at temperatures above 100 °C. Rates of electrochemical kinetics are enhanced, water management and cooling is simplified, useful waste heat can be recovered, and lower quality reformed hydrogen may be used as the fuel.

2nd International Conference on Fuel Cell Science, Engineering and Technology, 2004
Considerable interest exists in the application of single wall carbon nanotubes (SWNTs) to proton exchange membrane fuel cells (PEMFCs). Proposed applications include use as anode materials in both hydrogen and direct methanol fuel cells, solid polymer electrolyte additives, active cathode materials, and bipolar plate interconnects.
