Micro-Solid Oxide Fuel Cell: A multi-fuel approach for portable applications

The impact of oxygen ion transport at the electrolyte–electrode interface of a micro-solid oxide fuel cell using different fuels is investigated. Model validation is performed to verify the results versus the reported values. Furthermore, as the hydrogen-to-carbon ratio decreases, the diffusivity of the oxygen ion increases. This increase in diffusivity is observed because the number of hydroge...

Fuel processing microreactors for hydrogen production in micro fuel cell applications

The use of microreactors for in-situ and on-demand chemical processing and analysis is gaining increasing importance as the field of microreaction engineering matures from the stage of being regarded as a theoretical concept to a technology with significant industrial applications [1,2,3]. The objective of this work is to demonstrate a working microreaction system for use as a sustained source ...

A Micro Fuel Cell Power Supply Module for Low Power Portable Applications

This paper presents a power supply module targeted for low-power applications in the sub-mW range incorporating a passive μDMFC fuel cell (μFC) acting as energy source and a customized boost converter for the energy conversion. The low power budget of such energy sources mandates the adoption of efficient circuit solutions, hence the design of the boost converter is challenging. To maximize the...

A Self-Supported Direct Borohydride-Hydrogen Peroxide Fuel Cell System

A self-supported direct borohydride-hydrogen peroxide fuel cell system with internal manifolds and an auxiliary control unit is reported. The system, while operating under ambient conditions, delivers a peak power of 40 W with about 2 W to run the auxiliary control unit. A critical cause and effect analysis, on the data for single cells and stack, suggests the optimum concentrations of fuel and...
