# Formation of a Pt-Ni Catalyst in the Structure of a Silicon Micro-Fuel Cell

## TL;DR

This paper presents a new Pt-Ni catalyst for micro-fuel cells that replaces gold, improving durability and performance.

## Contribution

The novel contribution is the development of a Ni/PSi@Pt catalyst structure that eliminates gold usage in μ-FC electrodes.

## Key findings

- The Pt/Ni catalyst shows comparable or better durability than gold-based catalysts in porous silicon electrodes.
- Constructive technological solutions for forming the catalyst structure were successfully implemented.
- Comparative data highlights the effectiveness of the Pt/Ni catalyst over other composite types like Pt/Au.

## Abstract

This paper demonstrates the results of constructive technological research on the development of a catalyst with a Ni/PSi@Pt structure. This catalyst eliminates the use of gold in the structure of μ-FC electrodes. This work uses the main technological solutions for the formation of a gold-containing “core–shell” structure on the inner surface of pores. Comparative data on the results of assessing the durability of porous silicon electrodes with both Pt catalysts and composite catalysts of the Pt/In2O3, Pt/SnO2, Pt/Au and Pt/Ni types are also presented.
