Model-based topology development of a scalable methanol reformer

Clausthal University of Technology, together with IFT Whitecell Engineering GmbH, is developing a scalable methanol reformer for the efficient supply of hydrogen from green methanol. The hydrogen produced is intended for use in high-temperature polymer electrolyte membrane fuel cell (HT-PEM) systems.

The aim of this research and development project is a highly efficient, dynamically operable and durable reformer. The investigations initially focus on a power class of approximately 5 kW. The methods developed and the knowledge gained will subsequently be transferred to larger power classes of approximately 25 kW and beyond.

Modelling and Topology Development

At the Institute of Chemical and Electrochemical Process Engineering (ICVT), physicochemical models of the reforming process are being developed. They describe the interplay of reaction kinetics, mass transport, flow distribution and heat transfer. In addition to steady-state operation, start-up behaviour, load changes and the use of auxiliary electric heating are also considered.

The models form the basis for the systematic variation and optimisation of the reformer topology. Aspects under investigation include the arrangement of the reaction zones, the flow distribution, the heat transfer surfaces and the catalyst design. The goal is to identify suitable geometries and operating strategies and to assess their transferability to other power classes.

The Institute of Energy Process Engineering and Fuel Technology (IEVB) investigates the thermal coupling of the burner, combustion chamber and reformer. The models of both institutes are linked via defined thermal boundary conditions.

IFT Whitecell Engineering GmbH is responsible for the engineering design, prototype construction and the setup of the necessary testing infrastructure. Experimental measurement data are used to parameterise and validate the models. By combining modelling, design and experimental testing, development cycles are to be shortened and the reformer improved in terms of efficiency, operational reliability and scalability.
