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...
Temperature, flow and pressure are critical parameters that influence the performance of fuel cells, in terms of potential, current and power density, for example. Hence, the monitoring of non-uniform temperature/flow rate/pressure within a proton exchange membrane fuel cell (PEMFC) is crucial. To prevent degradation of the performance of a PEMFC, the size of sensors is reduced herein to a µm scale...
The production of useable energy is today a global issue and the search for alternative energy sources is very challenging. Therefore, scientists have' tried hard to identify new alternative energy sources. Fuel cells have potential as an indispensable source of electrical power. However, the mass production of fuel cells encounters various problems, which are yet to be solved, such as determining...
Among those problems regarding use of micro reformers that have not yet been solved include reducing their size, decreasing the amount of CO and combining the fuel cell, among others. Therefore, in this work, a micro temperature sensor and a heater are combined inside a stainless steel-based micro reformer to measure the temperature, to improve performance and minimize the concentration of CO. Micro-electro-mechanical-systems...
