Performance Test of Marine Fuel Cell System with LNG Reformer

Water-balance Assessment in a Reformer/Fuel-cell System

Abstract. In PEM fuel cells pure hydrogen is used as a fuel. Due to its low density, the density of its stored energy is low, too. One of the possible solutions to the problem is production of hydrogen from the energy-reach material, e.g. methanol. Conversion of methanol to hydrogen is made with reformer in a steam reforming process in which besides methanol there is also water needed. On the o...

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...

Spiral Methanol to Hydrogen Micro-Reformer for Fuel Cell Applications

Performance Characteristics of Lean Burn Engine Fuelled with Hydrogen Rich Gas from Plasma Fuel Reformer

In order to analyze the effect of hydrogen rich gas addition (HRG) on lean burn engine’s thermal efficiency and emission, an experimental research was conducted on a gasoline direct injection (GDI) engine using definite fraction of HRG. The results showed that HRG addition could significantly extend the lean operation limit, improve the engine’s lean burn ability, and decrease burn duration. HR...

Implementation of Adaptive Neuro-Fuzzy Inference System (Anfis) for Performance Prediction of Fuel Cell Parameters

Fuel cells are potential candidates for storing energy in many applications; however, their implementation is limited due to poor efficiency and high initial and operating costs. The purpose of this research is to find the most influential fuel cell parameters by applying the adaptive neuro-fuzzy inference system (ANFIS). The ANFIS method is implemented to select highly influential parame...
