Is this 80.000km-diameter world plausible?

Characteristics:

• has close to 80.000km in diameter

• The atmosphere is composed of:

  -30% hydrogen (cold gas planets have hydrogen but it makes sense it exists in a rocky planet?)

  -20% oxygen

  -49% nitrogen

  -1% carbon dioxide and others

• The planet round these temperatures: -90ºC and - 40 ° C

• The clouds are so many that occupy between 10 km and 100 km of the atmosphere, not letting the "sun" almost illuminate the ground, only a few mountains.
• Snowing and raining a lot.
• The "normal" winds are 50 km / hour.
• There are mountains that reach the 20,000 meters.
• Can live animals with a lot of body fat and hair (such as seals and polar bears) in areas with warm water lakes (heated by dormant volcanoes)
