Technological Monitoring Applied to Survey-Based on Brazilian Patent Applications about PEMFC
(Universidad Alberto Hurtado. Facultad de Economía y Negocios, 2011)
Comparative analysis between a PEM fuel cell and an internal combustion engine driving an electricity generator: Technical, economical and ecological aspects
(Elsevier B.V., 2014-02-05)
In the recent years the fuel cells have received much attention. Among various technologies, the Proton Exchange Membrane Fuel Cell (PEMFC) is currently the most appropriate and is used in several vehicles prototype. A ...
On-line fault diagnostic system for proton exchange membrane fuel cells
(ELSEVIER SCIENCE BV, 2008)
In this paper, a supervisor system, able to diagnose different types of faults during the operation of a proton exchange membrane fuel cell is introduced. The diagnosis is developed by applying Bayesian networks, which ...
Proton exchange membrane fuel cells (PEMFC)Celdas de combustible tipo membrana de intercambio protónico
(Pereira : Universidad Tecnológica de Pereira, 2007)
Las celdas de combustible son dispositivos que generan energía eléctrica y calor a partir de la reacción química entre el hidrógeno y el oxígeno y cuyo subproducto es agua (2H2 + O2 -> 2H2O). Este artículo pretende mostrar ...
Potential oscillations in a proton exchange membrane fuel cell with a Pd-Pt/C anode
(ELSEVIER SCIENCE BV, 2011)
We report in this paper the occurrence of potential oscillations in a proton exchange membrane fuel cell (PEMFC) with a Pd-Pt/C anode, fed with H(2)/100 ppm CO, and operated at 30 degrees C. We demonstrate that the use of ...
Self-assembled films from chitosan and poly(vinyl sulfonic acid) on Nafion® for direct methanol fuel cell
(Sociedade Brasileira de Química, 2012)
Chitosan/poly(vinyl sulfonic acid) (PVS) films have been prepared on Nafion® membranes by the layer-by-layer (LbL) method for use in direct methanol fuel cell (DMFC). Computational methods and Fourier transform infrared ...
Design of an integrated power system using a proton exchange membrane fuel cell
Integrated power systems could be a solution to provide energy to remote communities based on the use of renewable energies (such as wind or sun). This work proposed the design of one of those systems including alkaline ...
Fault-tolerant unfalsified control for PEM fuel cell systems
(Institute of Electrical and Electronics Engineers, 2015-01)
This paper addresses the implementation of a data-driven control strategy in a real test bench based on proton exchange membrane fuel cells (PEMFCs). The proposed control scheme is based on unfalsified control, which allows ...
