Overview

Our Alternative Power portfolio delivers advanced filtration, membrane, and thermal management technologies designed to optimize the performance and longevity of next-generation energy systems, including hydrogen fuel cell, battery electric, and alternative fuel applications.

Our team partners closely with OEMs to design, develop, and optimize custom systems in many on and off-highway global sectors. With advanced modeling, prototyping, and testing capabilities, we ensure our technologies seamlessly integrate into application-specific solutions.

Products

Donaldson offers customized solutions that incorporate high efficiency media and carbon layers to effectively address the sources of fuel cell contamination.

Hydrogen Fuel Filters

High pressure H2 filter up to 420 Bar. Low pressure H2 filter up to 25 Bar. Off-the-shelf filters available in 8 sizes (diameter 90 to 186 mm, length 159-404 mm).

Suitable for compressed hydrogen flow rate from 4 to 160 kg/h (1 to 45 g/s)
Low restriction due to pleated design of serviceable filter elements
Liquid aerosols removal by coalescing, efficiency ISO 12500-1 ranging 90 to 99.9%

Cathode Air Filters

Donaldson’s cathode fuel cell filters enable commercial vehicles to drive up to 300,000 km before a service interval, ensuring superior engine protection and reduced maintenance costs.

3 standard cathode air filters with option of customization
Compact and designed to simplify serviceability
Able to fit custom housings

Water Separators

Donaldson’s tailpipe water separator solution is designed to remove liquid condensed water from the vehicle tailpipe for efficient water management.

Operating temperature: Up to 95°C
Compact and modular design to remove liquid droplets from the gas stream
Potential to filter out any residue PFAS from water with additional filter

ePTFE Membrane

Our Tetratex® ePTFE membrane is engineered for vapor permeance and separation of gases and is easily integrated into flat sheet humidifiers. Donaldson offers:

Thin membranes that support high current density requirements
Flexibility to specify the ePTFE membrane independent of the coating, allowing OEMs to choose the optimal membrane/coating solution, rather than a pre-set (unoptimized) solution

Fuel Cell & Battery Venting

Donaldson offers engineering support and design customization of its integrated venting solutions for multiple industry applications including:

Battery electric vehicles
Hybrid electric vehicles
Heavy duty vehicles battery
Energy storage systems
Commercial battery packs

Humidifier

Humidifiers help protect fuel cell stacks by allowing the transfer of water vapor from the humid exhaust air to the cathode intake air system. A flat sheet humidifier starts with raw expanded polytetrafluoroethylene (PTFE) membrane.

Donaldson’s Tetratex® ePTFE membrane is:
Engineered for vapor permeance and separation of gases
Easily integrated into flat sheet humidifiers

Coolant Ion Exchanger

Our advanced coolant ion exchanger is engineered for efficient serviceability, featuring a toolless design that allows access from both the top and bottom.

Design: Cartridge style, serviceable
Compatibility: Suitable for glycol-based fuel cell coolant liquids
Effectively removes free ions from the coolant to keep electric conductivity low

Applications
