In this paper the design and the operation of the drive system in a Fuel Cell Electric Vehicle (FCEV) is presented. The system consists of a Proton Exchange Membrane Fuel Cell (PEMFC) stack, an interleaved boost converter, battery pack connected via a bidirectional buck-boost converter and a brushless DC motor (BLDC) driven by a three phase inverter. A basic analysis of each component of the in...

A better performance of photovoltaic (PV) generator is obtainedat high insolation. But at high insulation, the temperature of the PV system increases and leads to the drop down of the performance of the system making the system unable to supply the load. The problem becomes more difficult with irregular solar insolation, the system experience variation in his output, which is not good for the u...

In the chemical reaction that proceeds in a high-temperature proton exchange membrane fuel cell stack (HT-PEMFC stack), the internal local temperature, voltage, pressure, flow and current nonuniformity may cause poor membrane material durability and nonuniform fuel distribution, thus influencing the performance and lifetime of the fuel cell stack. In this paper micro-electro-mechanical systems ...

Distribution of contact pressure between the bipolar plate and gas diffusion layer considerably affect the performance of proton exchange membrane fuel cell. In this regard, an adaptive neuro-fuzzy inference system (ANFIS) is developed to predict the contact pressure distribution on the gas diffusion layer due to dimensional errors of the bipolar plate ribs in a proton exchange membrane fuel ce...

The proton exchange membrane fuel cell (PEMFC) demonstrates high commercial competitiveness due to its advantages: low operating temperature, power/mass ratio, fast response, no emission, and noise. Thermal water management remains a challenging issue for ensuring the cell’s performance at steady-state dynamic conditions. cathode moisture condensation uses semiconductor cooler effectively remov...

In this study, the control of thermal behavior for Proton Exchange Membrane Fuel Cells (PEMFC) is investigated. A description of the thermal behavior for PEMFC is given thanks to a nonhomogenous bilinear state space representation. In order to perform a local stabilization of the thermal behavior in a convex polytope of parameters, a linear approximation is proposed. Linear Matrix Inequality ba...

The distribution of temperature and voltage of a fuel cell are key factors that influence performance. Conventional sensors are normally large, and are also useful only for making external measurements of fuel cells. Centimeter-scale sensors for making invasive measurements are frequently unable to accurately measure the interior changes of a fuel cell. This work focuses mainly on fabricating f...
