Title: High-Performance Hydroxide Exchange Membrane Fuel Cells through Optimization of Relative Humidity, Backpressure and Catalyst Selection

Abstract

Hydroxide exchange membrane fuel cells (HEMFC) are an enticing power source for automobiles due to their low cost. Here we focus on improving the beginning-of-life performance of HEMFCs to a higher level with poly(aryl piperidinium) (PAP) membranes and ionomers. We reveal that lower RH and backpressure in anode than cathode can eliminate anode flooding and cathode dryout so that a balanced water management can be achieved. We also find that PtRu/C is a better anode catalyst than Pt/Ketjen Black due to the presence of Ru and Pt/Vulcan XC-72 is a better cathode catalyst than Pt/Ketjen Black due to its better mass transport properties. Once the preferred operating conditions and materials incorporated into the same cell, our HEMFCs achieved a peak power density of 1.89 W cm^–2 in H₂/O₂ and 1.31 W cm^–2 in H₂/air.

Poly(aryl piperidinium) membranes and ionomers for hydroxide exchange membrane fuel cells

Journal Article Wang, Junhua ; Zhao, Yun ; Setzler, Brian P. ; ... - Nature Energy

One promising approach to reduce the cost of fuel cell systems is to develop hydroxide exchange membrane fuel cells (HEMFCs), which open up the possibility of platinum-group-metal-free catalysts and low-cost bipolar plates. However, scalable alkaline polyelectrolytes (hydroxide exchange membranes and hydroxide exchange ionomers), a key component of HEMFCs, with desired properties are currently unavailable, which presents a major barrier to the development of HEMFCs. Here we show hydroxide exchange membranes and hydroxide exchange ionomers based on poly(aryl piperidinium) (PAP) that simultaneously possess adequate ionic conductivity, chemical stability, mechanical robustness, gas separation and selective solubility. Here, these properties originate from themore »« less

High-performance, low Pt content catalysts for the electroreduction of oxygen in polymer-electrolyte fuel cells

Journal Article Fournier, J ; Faubert, G ; Tilquin, J Y ; ... - Journal of the Electrochemical Society

Pt-included and Pt-supported catalysts have been synthesized using graphite and carbon black supports of various specific areas. The graphites are KS6 (20 m{sup 2}/g), HS100 (110 m{sup 2}/g), and HS300 (305 m{sup 2}/g) from Lonza, and the carbon blacks are Vulcan (254 m{sup 2}/g) and Black Pearls (1475 m{sup 2}/g) from Cabot. The Pt-included and Pt-supported catalysts were used at the cathode of a H{sub 2}/O{sub 2} fuel cell, and their polarization curves were compared to each other and to those of various Pt-supported catalysts from E-TEK.

Rheological Investigation on the Microstructure of Fuel Cell Catalyst Inks

Journal Article Khandavalli, Sunilkumar ; Park, Jae Hyung ; Kariuki, Nancy N. ; ... - ACS Applied Materials and Interfaces

We present a rheological investigation of fuel cell catalyst inks. The effects of ink parameters, which include carbon black-support structure, Pt presence on carbon support (Pt-carbon), and ionomer (Nafion) concentration, on the ink microstructure of catalyst inks were studied using rheometry in combination with ultrasmall-angle X-ray scattering (USAXS) and dynamic light scattering (DLS). Dispersions of a high-surface-area carbon (HSC), or Ketjen black type, demonstrated a higher viscosity than Vulcan XC-72 carbon due to both a higher internal porosity and a more agglomerated structure that increased the effective particle volume fraction of the inks. The presence of Pt catalyst on bothmore »« less

Characterization of fuel cell electrocatalysts using x-ray methods

Conference Garzon, F H ; Brosha, E L ; Zawodzinski, C ; ...

High surface area electrocatalysts are critical components of high efficiency low cost polymer membrane fuel cells. The platinum and/or platinum alloy catalysts are typically prepared as nanocrystalline carbon supported and unsupported anode and cathode materials. The choice of catalyst type depends on whether the application is for hydrogen or direct methanol fuel cells (DMFCs). 2 nm crystallite size Pt supported on Vulcan XC-72 carbon is the anode and cathode catalyst most commonly used for hydrogen fuel cells while Pt-Ru alloys of 3-5 nm are currently being used for anode catalysts in DMFC systems. Key parameters for successful catalyst design aremore »« less

Pt inclusion compounds as oxygen reduction catalysts in polymer-electrolyte fuel cells

Journal Article Faubert, G ; Guay, D ; Dodelet, J P - Journal of the Electrochemical Society

Pt inclusions in high-specific-area graphite (HS300, from Lonza) and Vulcan (XC-72R, from Cabot) have been synthesized by the reduction of PtCl{sub x} salts intercalated in these hosts. These materials perform well as catalysts for the reduction of oxygen in polymer-electrolyte fuel cells (PEFCs). After an activation time of 48 h during which the cathode is held at 0.5 V vs. the reference hydrogen electrode, it is found that catalysts based on Pt inclusions and commercial catalysts of the same Pt content and loading have similar mass and specific activities. However, in the same conditions, catalysts based on Pt inclusions performmore »« less
