The development of economical bipolar plates for fuel cells
One of the major challenges in the production of economical polymer electrolyte membrane (PEM) fuel cells for automotive applications is the development of materials for the generation of bipolar plates which meet all the property requirements and can be readily manufactured to impart fine channels for transporting hydrogen and oxygen. Bipolar plates can be made from various materials with the ...
متن کاملMicrofabrication of Microchannels for Fuel Cell Plates
Portable electronic devices such as notebook computers, PDAs, cellular phones, etc., are being widely used, and they increasingly need cheap, efficient, and lightweight power sources. Fuel cells have been proposed as possible power sources to address issues that involve energy production and the environment. In particular, a small type of fuel-cell system is known to be suitable for portable el...
متن کاملBipolar Plates
• good electrical conductivity (>100 S cm 1 bulk conductivity), • high thermal conductivity (>20 W cm ), • high chemical and corrosion resistance, • mechanical stability toward compression forces, • low permeability for hydrogen, • low-cost material being processable with mass production techniques, • low weight and volume, and • recyclable materials. Two different kinds of materials have been ...
متن کاملCompact bipolar plate-free direct methanol fuel cell stacks.
Fuel cells with a PtAu/C anode and a Pr-doped Mn(2)O(3)/C cathode were stacked without using a bipolar plate, and their discharge properties were investigated in a methanol aqueous solution bubbled with air. A three-cell stack exhibited a stack voltage of 2330 mV and a power output of 21 mW.
متن کاملDevelopment of bipolar plates for fuel cells from graphite filled wet-lay material and a thermoplastic laminate skin layer
In this paper, a method with the potential to rapidly produce thermoplastic polymer composite bipolar plates with improved formability and hrough-plane conductivity is described. In our earlier work, it was reported that composite bipolar plates made with graphite filled wet-lay materials xhibited excellent mechanical properties and in-plane electrical conductivity. However, the through-plane c...
