Proton exchange membrane (PEM) fuel cells can operate at low temperatures and are scalable. Therefore, they can be used in a wide range of applications, such as portable, automotive and stationary ...

In the generic PEM fuel cell pictured at left, the membrane lies sandwiched between a positively charged electrode (the cathode) and a negatively charged electrode (the anode). In the simple ...

Figure 2A. Schematic of the STR PEM fuel cell reactor. The exposed membrane area was ~1.5 cm 2, with gas volumes above the anode and cathode of ~0.2 cm 3. The MEA employed Etek electrodes and a Nafion ...

The cathode electrode is the main source of performance loss in PEM fuel cells and this is due to low utilisation of the catalyst and the slow reaction rate. The main objective of this project is ...

Renewable energy technologies are of great importance to society in order to reduce emissions of CO2 and other pollutants in Germany, Europe and worldwide. Hydrogen is used to effectively store energy ...
