Description of Gasket Failure in a 7 Cell PEMFC Stack
This article presents the data and the description of a fuel cell stack that failed due to gasket degradation. The fuel cell under study is a 7 cell stack. The unexpected change in several variables such as temperature, pressure and voltage indicated the possible failure of the stack. The stack was monitored over a six hour period in which data was collected and consequently analyzed to conclud...
متن کاملExperimental Investigation into a Novel Modular PEMFC Fuel Cell Stack
The Polymer Electrolyte Membrane Fuel Cell (PEMFC), despite being regarded as an ideal replacement to the internal combustion engine, is still not an economically attractive prime-mover due to a number of key challenges that have yet to be fully resolved; such as degradation to cell components resulting in inadequate lifetimes, specialised manufacturing processes and poor gravimetric/volumetric...
متن کاملExperimental evaluation into novel, low cost, modular PEMFC stack
The Polymer Electrolyte Membrane Fuel Cell (PEMFC), despite being regarded as an ideal replacement to the internal combustion engine, is still not an economically attractive pri-mover due to a number of key challenges that have yet to be fully resolved; some of which include degradation to cell components resulting in inadequate lifetimes, specialised and costly manufacturing processes and poor...
متن کاملThermal management issues in a PEMFC stack – A brief review of current status
Understanding the thermal effects is critical in optimizing the performance and durability of proton exchange membrane fuel cells (PEMFCs). A PEMFC produces a similar amount of waste heat to its electric power output and tolerates only a small deviation in temperature from its design point. The balance between the heat production and its removal determines the operating temperature of a PEMFC. ...
متن کاملCurrent Status and Fundamental Research Needs in Thermal Management within a Pemfc Stack
Understanding the thermal effects is critical in optimizing the performance and durability of proton exchange membrane fuel cells (PEMFCs). A PEMFC produces a similar amount of waste heat to its electric power output and tolerates only a small deviation in temperature from its design point. These stringent thermal requirements present a significant heat transfer challenge. The heat balance also...
