Reformate Gas

The PEM fuel cell has broad applications such as stationary power generation, transportation power sources and portable power generators. From commercial considerations, most anodes of PEM fuel cells use reformate gas as their fuels. However, reformate gas will have small content of carbon monoxide (CO) which will seriously poison platinum (Pt) catalyst electrode, and result in cell performance degradation significantly. The anode air-bleeding method is a preferable way to solve this CO-poisoning problem due to its simplicity, low cost and effectiveness. In this study, a test PEM fuel cell (single cell, active area 5cm × 5 cm) is assembled, its anode fuel uses hydrogen with 52.7ppm CO. Air-bleeding method then is applied to investigate and analyze the influence of CO poisoning on the performance of this PEM fuel cell.

Novel Catalyst

ABSTRACTMiniature and microscale fuel processors that incorporate novel catalysts and microtechnology-based designs are discussed. The novel catalyst allows for methanol reforming at high gas hourly space velocities of 50,000 hr-1 or higher while maintaining a carbon monoxide levels at 1% or less. The microtechnology-based designs extremely compact and lightweight devices. The miniature fuel processors, with a volume less than 25 cm3, a mass less than 200 grams, and thermal efficiencies of up to 83%, nominally provide 25 to 50 watts equivalent of hydrogen, which is ample for the portable power supplies described here. With reasonable assumptions on fuel cell efficiencies, anode gas and water management, parasitic power loss, the energy density was estimated at 1700 Whr/kg. These processors have been demonstrated with a CO cleanup method and a fuel cell stack. The microscale fuel processors, with a volume of less than 0.25 cm3 and a mass of less than 1 gram, are designed to provide up to 0.3 watt equivalent of power with efficiencies over 20%.

Fuel Cell Operation

As fuel cells are increasingly commercialized for various applications, harmonized and industry-relevant test procedures are necessary to benchmark tests and to ensure comparability of stack performance results from different parties. This paper reports the results of parametric sensitivity tests performed based on test procedures proposed by a European project, Stack-Test. The sensitivity of a Nafion-based low temperature PEMFC stack’s performance to parametric changes was the main objective of the tests. Four crucial parameters for fuel cell operation were chosen; relative humidity, temperature, pressure, and stoichiometry at varying current density. Furthermore, procedures for polarization curve recording were also tested both in ascending and descending current directions.
