Using Data

Fuel cell systems for residential applications are an emerging technology for which specific consumer-oriented performance standards are not well defined. This paper presents a proposed experimental procedure and rating methodology for evaluating residential fuel cell systems. In the proposed procedure, residential applications are classified as grid independent load following; grid connected constant power; grid connected thermal load following; and grid connected water heating. An experimental apparatus and procedures for steady state and simulated use tests are described for each type of system. A rating methodology is presented that uses data from these experiments in conjunction with standard residential load profiles to quantify the net effect of a fuel cell system on residential utility use. The experiments and rating procedure are illustrated using data obtained from a currently available grid connected thermally load following system.

Abstract In this work the optimization-based, integrated concurrent design method is extended to a general mechanical system — the transportation fuel cell system. A general optimal design model considering both functional performance and production costs is first introduced. Mathematical models of the functional performance and production costs of the Ballard fuel cell system are then discussed. A joint performance and cost optimization is carried out using the Ballard fuel cell system to demonstrate the approach. The optimization concurrently takes into account of two functional performance aspects and production costs to identify the optimal values of two key design variables. The work is a continuation of the authors’ earlier research on integrated concurrent engineering design.
