Journal ArticleDOI

A comprehensive review of PBI-based high temperature PEM fuel cells

Samuel Simon Araya, +8 more
- 14 Dec 2016 - 
TL;DR: In this article, the authors present the current status on the understanding of the various operational aspects of high temperature proton exchange membrane fuel cells (HT-PEMFCs) and an overview of the common practices of their design and characterization techniques at single cell, stack and system levels.
Journal ArticleDOI

Fault detection and isolation of high temperature proton exchange membrane fuel cell stack under the influence of degradation

Christian Jeppesen, +5 more
- 15 Aug 2017 - 
TL;DR: In this paper, the authors proposed a data-drive impedance-based methodology for fault detection and isolation of low and high cathode stoichiometry, high CO concentration in the anode gas, high methanol vapour concentrations in the Anode gas and low anode stoicheometry, for high temperature PEM fuel cells.
Journal ArticleDOI

Experimental study to distinguish the effects of methanol slip and water vapour on a high temperature PEM fuel cell at different operating conditions

Sobi Thomas, +3 more
- 15 Apr 2017 - 
TL;DR: In this article, the effects of methanol and water vapour on a high temperature polymer electrolyte membrane fuel cell under different temperatures (160°C and 180°C) and current densities (0.2
Journal ArticleDOI

Fault Characterization of a Proton Exchange Membrane Fuel Cell Stack

Samuel Simon Araya, +5 more
- 02 Jan 2019 - 
TL;DR: In this paper, the main faults in a commercial proton exchange membrane fuel cell (PEMFC) stack for micro-combined heat and power ( μ -CHP) application are investigated, with the scope of experimentally identifying fault indicators for diagnosis purposes.
Journal ArticleDOI

An experimental and simulation study of novel channel designs for open-cathode high-temperature polymer electrolyte membrane fuel cells

Sobi Thomas, +7 more
- 01 Mar 2016 - 
TL;DR: In this paper, two unique parallel serpentine flow designs were developed to yield a low pressure drop and uniform flow distribution, one without pins and another with pins, and a five-cell stack was fabricated in the lab based on the new design.
