Methanol has many advantages, such as safe for storage and transportation and low reforming temperature. Methanol can be use to provide hydrogen for fuel cell. In this research, the multifunction micro-sensors are integrated using the micro-electro-mechanical systems (MEMS) technology for the in-situ monitoring of temperature, flow and pressure within micro reformer. The multifunction micro-sensors...
Polymer lithium-ion batteries must rapidly charge and discharge, rapidly increasing their inner temperature. This heating raises a safety issue. Therefore, a flexible micro temperature sensor for the in-situ monitoring of temperature within a polymer lithium-ion battery must be developed. Traditional thermocouples are too large to be used to measure temperature inside polymer lithium-ion batteries...
Mass production of micro-reformers raises various problems still unsolved, such as the evaluation of their internal temperature and flow rate. Such issues influence the efficiency of micro reformers. To our knowledge, no investigation has elucidated the internal operation of micro reformers. Hence, this work fabricates micro flow sensors on a flexible substrate using the micro-electro-mechanical systems...
Pressure and flow rate are critical parameters associated with the performance of proton exchange membrane fuel cells (PEMFCs). Fuel cell flooding can be diagnosed by monitoring pressure drops. Flow rate is related to optimized operation of fuel cells and fuel cell aging. Previous research measured pressures at the flow channel inlet and outlet. However, determining the pressure distribution and flow...
