Hydrogen Fuel Cell Development
1. Hydrogen Fuel Cell
Issue
- High manufacturing cost
- Sensitivity to operating conditions
- Limitations of long-term operation
Purpose
- Availability of installation in vehicles
and buildings
- Improved durability, power density,
and performance
- Long-term operability
- Building price competitiveness for
manufacturing
Major technology
- Membrane with low ohmic resistance,
reduced hydrogen crossover, and
good durability
- Low manufacturing cost and chemical
stability of catalyst
- Stack and membrane electrode
assembly (MEA) capable of
continuous operation at high
temperature, sub-zero temperature,
and low/non relative humidity
2. Liquid Hydrogen Tank used in Fuel Cell Vehicles
Issue
- Explosion of existing H2 gas storage
Purpose
- Loading of liquid hydrogen
(below -253 °C)
- Availability of transportation by vehicles,
e.g., car, truck, train, and ship
Major technology
- Cold insulation technology
- A standard container structure
optimization
- Pressure vessel design
- Internal pressure monitoring pneumatic
operating
