A novel approach on the determination of the minimal

In this article, a novel mathematical approach is proposed to determine the minimal proton exchange membrane fuel cell efficiency below which it is not recommended to operate the fuel cell. The objective of this proposal is to minimize the annual fuel cost and the electricity cost of a proton exchange membrane (PEM) fuel cell since both terms are efficiency dependent.

Fuel cells (FC), particularly those based on hydrogen, have long been heralded as the solution for electric transportation. While batteries have stolen the scene in recent years, IDTechEx has identified a number of applications where FCs can offer a better solution than Li-ion batteries, especially when it comes to range and fast refuelling. We believe this market can potentially boom to reach

Bipolar plates for PEM fuel cells: A review

2005/9/1A significant part of the PEMFC fuel cell stack is the bipolar plates (BPs), which account for about 80% of total weight and 45% of stack cost . They are designed to accomplish many functions, such as distribute reactants uniformly over the active areas, remove heat from the active areas, carry current from cell to cell and prevent leakage of reactants and coolant.
