MEMS-Based Fuel Reformer with Suspended Membrane Structure

A Compact Reformer for Portable Fuel Cells

A compact reformer to generate hydrogen for portable fuel cell applications is presented. This reformer is a conventional type single-path tubular reactor packed with granular catalyst particles in which steam reforming and catalytic partial oxidation reactions take place in series using a mixture of methanol and water as a feed. The novel feature of this reformer is in the interlacing of the f...

MEMS-based Handy Fuel Adulteration Detection Device

Adulteration of automobile fuels, especially petrol and diesel is a rampant malpractice in India. The most commonly found forms are—mixing kerosene in diesel and diesel in petrol. With the rising prices of fuel and the subsidy on kerosene, getting away with even 10-15% adulteration is immensely profitable. While less than 10% adulteration is financially unattractive, more than 30% is easily det...

Release Optimization of Suspended Membranes in MEMS

Near-Optimal Controls of a Fuel Cell Coupled with Reformer using Singular Perturbation methods

A singularly perturbed model is proposed for a system comprised of a PEM Fuel Cell(PEM-FC) with Natural Gas Hydrogen Reformer (NG-HR). This eighteenth order system is decomposedinto slow and fast lower order subsystems using singular perturbation techniques that provides tools forseparation and order reduction. Then, three different types of controllers, namely an optimal full-order,a near-opti...
