Dynamics of Autohumidifed PEM Fuel Cell Operation
Start-up and dynamic responses to changes in load are reported for a dry feed, autohumidified polymer electrolyte membrane fuel cell PEMFC . The fuel cell current can be ignited by water injection; criteria are derived for the required water injection as functions of fuel cell size, temperature, and reactant feed rates. Steady-state multiplicity is observed where the fuel cell current can be ei...
متن کاملParametric Study of Operation and Performance of a PEM Fuel Cell Using Numerical Method
Output characteristics of fuel cells are affected by a large number of parameters such as geometry, dimensions, construction materials and conditions of supplying fluids. In this paper a mathematical model followed by a two-dimensional numerical approach has been presented to study the fuel cell parametrically. Effect of oxygen concentration at gas diffusion layer entrance, temperature and ...

متن کاملPEM fuel cell electrodes
The design of electrodes for polymer electrolyte membrane fuel cells (PEMFC) is a delicate balancing of transport media. Conductance of gas, electrons, and protons must be optimized to provide efficient transport to and from the electrochemical reactions. This is accomplished through careful consideration of the volume of conducting media required by each phase and the distribution of the respe...
متن کاملInvestigation and optimization of a PEM fuel cell’s electrical and mechanical behavior
Effect of clamping pressure on electrical resistance between Gas diffusion layer (GDL) and bipolar plate is a very important parameter in Proton exchange membrane (PEM) fuel cells. For investigation of this matter some researches have been done in these years. But there is not an experimental investigation of clamping pressure effect on PEM electrical resistance. In this paper, some experimenta...
