As a general summary the decreased demand in autocatalyst use is being more than off-set in other uses.
Here is an extract to provide why it's demand is increasing:
"There is potential for platinum demand to increase in 2018, based on a very positive outlook for industrial applications. It is likely to be a bumper year for the glass sector, with glass makers poised to make exceptionally large purchases of platinum for LCD and fibreglass expansions in China. The electrical sector will be boosted by strong growth in the fuel cell segment, where transport applications are forecast to consume more platinum than stationary fuel cells for the first time. Chemical demand will remain robust: new metal requirements from this industry are expected to exceed half a million ounces of platinum for a sixth consecutive year. Much of this year’s growth in platinum consumption in fuel cell electric vehicles (FCEVs) will come from China, mainly due to the roll-out of fuel cell bus programmes in a number of cities. This has generated orders for significant numbers of fuel cell stacks to be delivered over the 2018–2021 period. The outlook for fuel cells in China is increasingly positive: over the past year, developments in the government’s New Energy Vehicle policy have created a favourable environment for the development of a mass market for FCEVs. The use of fuel cells should be favoured by the need to meet strict criteria such as a minimum range and fast charging in order to qualify for the most generous subsidies and incentives available. In contrast, we expect financial support for battery electric and plug-in hybrid vehicles to be reduced, and eventually removed. The Chinese government’s aim is to increase the number of FCEVs on Chinese roads to 50,000 units by 2025, and one million by 2030."
