Humidification Optimization in Silicon-based Miniaturized Fuel Cell

Modeling and Identification of a Pem Fuel Cell Humidification System

A theoretical model of a humidifier of Proton Exchange Membrane (PEM) fuel cell systems is developed and analyzed first in this paper. The model shows that there exists a strong nonlinearity in the system. Then, the system is identified using a wavelet networks method. To avoid the curse-of-dimensionality problem, a class of wavelet networks proposed by Billings is employed. The experimental da...

Effect of temperature on a miniaturized microbial fuel cell (MFC)

A microbial fuel cell (MFC) is a bioinspired energy converter which directly converts biomass into electricity through the catalytic activity of a specific species of bacteria. The effect of temperature on a miniaturized microbial fuel cell with Geobacter sulfurreducens dominated mixed inoculum is investigated in this paper for the first time. The miniaturized MFC warrants investigation due to ...

Miniaturized time-scanning Fourier transform spectrometer based on silicon technology.

We present a miniaturized Fourier transform spectrometer (FTS) based on optical microelectromechanical system technology. The FTS is a Michelson interferometer with one scanning mirror. A new type of electrostatic comb drive actuator moves the mirror. We have measured a nonlinearity of the driving system of +/-0.5 mum for a displacement of 38.5 mum . A method is presented to correct the spectru...

Characteristics of Pemfc Operation in Ambient and Low Pressure Environment Considering the Fuel Cell Humidification

This paper summarizes experimental results of an air fed polymer electrolyte membrane fuel cell system HyPM XR 12 (Hydrogenics Corp.) considering fuel cell temperature, stoichiometry and load requirement variations at ambient and low pressure operation. The experimental work realized at a low pressure test facility designed and assembled by the German Aerospace Center, Institute of Engineering ...
