Microflow-generator for fuel-cell methanol hydrogen microreactor

Design, fabrication and characterization of a low-cost, energy efficient flow-generator for hydrogen production in microreactors, is presented. Design guidelines for proposed MPC method, based on micropump and pressure sensor are discussed in detail, followed by experimental setup description and system characterization. It was found that micropumps stability has a significant impact on long term system performance. The proposed approach is energy efficient, measurements on MPC flow-generator revealed that 1ml/min flow rate through measuring valve at 0.0025 Cv factor setting can be reached at only 8,7mW electrical power consumption.
