Fuel Cell Engineering for Passenger Cars and Electric Vehicles
Proton exchange membrane fuel cells (PEMFC) generate efficient and emission-free power for electric vehicles. Fuel cell vehicles (FCV) represent the "all performance cars" in the e-mobility sector i.e. they reach driving ranges similar to conventional cars even in the larger vehicle classes.
As the development processes nears commercialization the major fuel cell development efforts are focused on cost reduction, lifetime and reliability optimization.
CFD analysis of PEMFC cells and components
The critical operating conditions of fuel cells lead to corrosion effects and reduction of stack lifetime. Many effects are related to problems with water management. Performance optimization therefore requires the identification of the problem(s) and their elimination by modification of cell design, material properties and operational parameters.

AVL THDA – FUEL CELL MONITORING
A critical operating status is usually monitored by measuring cell voltages individually. Large fuel cell stacks require costly and complicated measurement devices.
