Abstract

We apply a Design of Experiments method on the electrical potential equation of SOFC button cells in order to investigate how measurements may be improved regarding the parameter estimation of our model. With the use of a genetic algorithm we optimise the information matrix of measurements, resulting in a set of optimal measuring points and respective weighing factors. A study on the spectrum of measurements is also conducted for a number of 8 up to 46 measurement points. The results show that an experiment may be improved not only by a better targeted set of measurements, but also by elimination of unnecessary measurements. The presented methodology offers a better Design of Experiments for button cell measurements, but it may also be used to develop diagnostics tools for Fuel Cell stacks and systems.

Design of experiments

The design of experiments (DOE or DOX), also known as experiment design or experimental design, is the design of any task that aims to describe and explain the variation of information under conditions that are hypothesized to reflect the variation. The term is generally associated with experiments in which the design introduces conditions that directly affect the variation, but may also refer to the design of quasi-experiments, in which natural conditions that influence the variation are selected for observation.

Experiment

An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies.

Set theory

Set theory is the branch of mathematical logic that studies sets, which can be informally described as collections of objects. Although objects of any kind can be collected into a set, set theory, as a branch of mathematics, is mostly concerned with those that are relevant to mathematics as a whole. The modern study of set theory was initiated by the German mathematicians Richard Dedekind and Georg Cantor in the 1870s. In particular, Georg Cantor is commonly considered the founder of set theory.
