For automotive applications, it is necessary to maximize the fuel conversion efficiency of a PEM direct-methanol fuel cell (DMFC) over the broadest possible dynamic range of power. The research reported here critically examines the efficiency of the DMFC stack when operated over a broad power range. This research establishes a basis for a control strategy that simultaneously: optimizes DMFC fue...

Depletion of petroleum derived fuel and environmental concern has promoted to look over the biofuel as an alternative fuel sources. But a complete substitution of petroleum derived fuels by biofuel is impossible from the production capacity and engine compatibility point of view. Yet, marginal replacement of diesel by biofuel can prolong the depletion of petroleum resources and abate the radica...

The adoption of fuel cells (FCs) for industrial applications, transportations and home power generation is widely increased during recent years. Because FCs are still in the development stage, to evaluate and validate fuel cell technologies suitable test systems are needed. In a fuel cell both chemical and electric sections can be founded, so to control its behaviour the measurement of differen...

In recent years alternative fuels and corresponding alternative automotive technologies have been seen as major potential contributors to head towards a sustainable transport system. The core objective of this paper is to investigate the perspectives of different alternative fuels and automotive technologies in a dynamic framework till 2050 in comparison to fossil fuel driven conventional cars ...

Low cost, durable, and selective membranes with high ionic conductivity are a priority need for wide-spread adoption of polymer electrolyte membrane fuel cells (PEMFCs) and direct methanol fuel cells (DMFCs). Electrolyte membranes are a major cost component of PEMFC stacks at low production volumes. PEMFC membranes also impose limitations on fuel cell system operating conditions that add system...
