The key challenge in improving power density is combining with operation at low air flow rates in order to maintain a water balance, and achieve attractive system mass and size. Improved catalysts and membranes with low methanol permeability are key to achieving these improvements. Challenges relating to miniature DMFC for battery replacement are discussed. Possibilities of reduction in catalyst and membrane cost suggest that premium power applications (100 W-5 kW) could be an early point of entry for DMFC into commercial markets.","PeriodicalId":368992,"journal":{"name":"Fifteenth Annual Battery Conference on Applications and Advances (Cat.

Kalhammer","doi":"10.1109/BCAA.2000.838375","DOIUrl":"https://doi.org/10.1109/BCAA.2000.838375","url":null,"abstract":"This paper reviews the status and prospects of high-power batteries intended for application in power trains for hybrid electric vehicles. It is based on a survey of a d v a d batteries conducted by the author for the Califomia Air Resources Board in the first half of 1999. Hybrid electric vehicle (HEV) concepts and technology are still evolving, as are the associated requirements for energy storage. The most important requirements atablished or implied for several generic HEV typa are discussed to help judge the applicability of candidate batteries. On that basis, high power versions of nickel-metal hydride, lead acid, and lithium ion batteries meet the performance requirements for the power assidregeneration BEV application. Nickel-metal hydride, lithium ion and lithium polymer batteries appear suited for hybrid electric vehicles that have significant driving range on battery power alone. The status of these technologies and their prospects for availability w i t h the nexl 3-5 years are discussed. The emergence of hybrid electric vehicles promises viable markets for advanced batteries (as well as for electric power conversion, control and motor technologies) in electric transportation Hybrid electric vehicles especially those with significant battery-only driving range also might become stepping stones in the commercial introduction of electric vehicles that take advantage of the remarkable advances in battery technolog achieved over the past five years. Introduction The successful introduction of Toyota’s PRIUS hybrid vehicle in Japan and the announcements by Ronda and Toyota of plans to introduce their hybrid vehicles in the U.S. market have dramaiically increased interest in this new automotive product. Automobile mnufacturets, regulators and environmentalists see HEVs as a potentially major avenue to increasing vehicle energy efficiency and reducing the emissions of air pollutants. Enam and environmental policy leaders view HEVs especialiy those that derive a significant portion of the propulsion energy from electricity as a stratqy to replace imported oil with domestic energy resources and reduce the emissions of carbon dioxide. Final@, electric utilities consider grid-connected hybrid electric vehicles a possible business opportunity. Batteries are an essential component of the hybrid electric vehicle types currently under development. In the functionally simplest KEV concept, the battery is employed to store energy captured in regenerative braking plus make-up energy provided by the engine, to keep the battery at approximately 50% state-ofcharge (SoC). The stored energy is used as needed to start the vehicle’s combustion engine and assist the engine during acceleration. The Toyota PRIUS and Honda’s recently announced INSIGHT HEV are exampIes of this “Power AssisuRegmration” (PAIR) -hybrid electric vehicle. Most of the hybrid vehicles currently under development at the three major U.S. carmakers also fall in this cntegoty.

This work has resulted in new paste compositions for both positive and negative plates, which provide higher material utilization and better capacity-maintenance during cycling. The new positive paste is water-based using a pre-sulfated lead compound, with a conductive additive which improves the charge efficiency during formation. The negative paste is also water-based paste, using a pre-sulfated lead compound, and has a modified expander to improve formation efficiency. The material utilization efficiencies of both negative and positive active mass as obtained from the bipolar work are described. An initial experiment using this new paste on grid-type plates in a 12V/26Ah battery has demonstrated significant performance improvement over an identical commercial battery. Simplification and improvement of VRLA manufacturing processes also appear possible using the BPI paste.","PeriodicalId":368992,"journal":{"name":"Fifteenth Annual Battery Conference on Applications and Advances (Cat.

Single cell data for a membrane electrode assembly (MEA) that can operate at low air stoichiometry is presented.

Single cells with a 25-cm/sup 2/ active area have been operated in this regime and can maintain an average cell voltage of 0.43 V at 100 mA/cm/sup 2/ for 120 minutes with a cell voltage decay of 0.2 mV/min. A five-cell stack with a 80-cm/sup 2/ active area, scaled up from the single cell, was capable of sustaining 100-mA/cm/sup 2/ load at a 1.75 air stoichiometry for over 70 hours, with a voltage decay of the order of 2 mV/hr. Voltage decay is reversible by purging excess water in the cathode.","PeriodicalId":368992,"journal":{"name":"Fifteenth Annual Battery Conference on Applications and Advances (Cat.
