摘要：

A MEMS-based chemical concentration sensor for monitoring and controlling the methanol to water ratio in a Direct Methanol Fuel Cell (DMFC) is described. This sensor is based on a vacuum packaged resonant microtube and on-chip platinum temperature sensor to measure the density of a fluid. Using the density and temperature output the methanol concentration is determined. The performance of the sensor over temperature, concentration and in the presence of formic acid by-products is examined. Additional test results and applications for other fuels and biofuels are presented including ethanol, ethylene glycol, butanol, gasoline and diesel fuel. (c) 2007 Elsevier B.V. All rights reserved.
