− The achievement of a proper and uniform pressure distribution between the membrane electrode assembly (MEA) and the bipolar plates of a proton exchange membrane fuel cell (PEMFC) is a key factor of stack design and assembly. Contact pressure levels are usually controlled by selecting an appropriate external clamping pressure on the endplates. Very few studies have been focused on the measurem...

The operating parameters have an important impact on the performance of a proton exchange membrane fuel cell (PEMFC). This paper investigates experimentally and numerically temperature relative humidity which significant influence PEMFC current density. These are adjusted simultaneously dynamically during operation. A 50 cm2 active area single-cell with serpentine flow channel was studied. In o...

(Received: October 13, 2011; Accepted: November 25, 2011) Abstract: The performance of the continuous stirred tank reactor (CSTR) for the in-situ production of hydrogen gas (H ) integrated with a polymer electrolyte membrane fuel cell (PEMFC) was investigated. Facultative 2 anaerobe fermentation of Enterobacter aerogenes ADH-43 was conducted into CSTR 50 rpm of agitation speed, 37°C of temperat...
