Christina Johnston, PhD

I manage and contribute to research in electrochemistry and materials, which includes fuel cells, batteries, and emerging topics. Previously at LANL, I focused on fuel cells, especially catalysts, supports, and electrodes. At Bosch, my team engages in electrochemical material and device development (e.g. fuel cell, battery, water purification), material property measurement, and advanced characterization.

Please tell us what fascinates you most about research.

I enjoy the process of transforming an idea into reality, especially through teamwork. This applies equally to inventing new materials, gaining understanding of existing materials to use them more effectively, and combining these elements to create an entirely new or best-in-class device.

What research topics are you currently working on at Bosch?

We address lifetime challenges in fuel cells through electrochemistry and materials approaches, provide materials information that enables better usage of existing batteries, and develop new ideas for materials and devices, such as for water purification applications.

What are the biggest scientific challenges in your field of research?

The overall cost of the fuel cell must come down without reducing lifetime. This is difficult to achieve as reducing platinum and decreasing membrane thickness tend to decrease the durability of the fuel cell.

How do the results of your research become part of solutions "Invented for life"?

A widespread adoption of fuel cell vehicles would enable a significant net reduction in CO2 emissions versus fossil fuel vehicles, which would contribute to the mitigation of climate change. Additionally, fuel cell vehicles emit only water, unlike fossil fuel vehicles that emit particulate matter, VOCs, NOx, and SO2, which contribute to poor air quality and create health risks.
