The PEMFC (Polymer Exchange Membrane Fuel Cell) is one of the most researched generators in hydrogen technology. The PEMFCs offer low emissions, several applications in industry with high power density. The basic material for the construction of components in low-temperature fuel cells is carbon or its allotropic forms and carbon nanomaterials. Carbon materials are used to build diffusion layers of electrodes, as catalyst carriers, for the construction of covers/interconnectors and as fuel. In this work, the carbon materials used to build a single cell have been reviewed taking into account various methods of fabrication and modification of materials.

Fluorinated Carbon

ABSTRACTCarbon and fluorinated carbon materials are major constituents of phosphoric acid fuel cells and PEM fuel cells and the stability of these materials is critical for long life operation. Laboratory corrosion studies of separator plate materials were correlated with separator plate changes in commercial PAFC fuel cells. The addition of thin films of Teflon™ to the separator plates extends the life of the separator plates to 60,000+ hours through the formation of a temporary hydrophobic barrier. ESCA studies show the loss of hydrophobicity with time of PAFC electrodes to be a result of delamination of the Teflon from the carbon and not corrosion of the Teflon by phosphoric acid. The projected life of PAFC power plants has been confirmed by commercial operation of power plants for over 40,000 hours.
